1. 1. Configuration Example of Information Collection System 1-1 First Example FIG. 1 shows a first example of a configuration of an information collection system including the recording / reproducing apparatus according to the present embodiment. This is a basic configuration of the information collection system according to the embodiment. FIG. 1 shows a state in which an Internet homepage (server) 100 and an Internet terminal device 300 are communicably connected via the Internet 200 forming an information environment as a communication network. The Internet homepage 100 here is a homepage (information source) that provides information to be collected and stored in a downloadable disk 90A described later.
Internet address code (URL; Uniform Resour) stored in download-compatible disk 90A
ce Locator).

The Internet terminal device 300 has a function for performing mutual communication with the homepage via the Internet 200. The recording / reproducing apparatus 1 is a recording / reproducing apparatus that can perform recording / reproducing in correspondence with MD. Further, in this case, the terminal device is connected to the Internet terminal device 300 via a data interface or the like so that data can be mutually transmitted. The internal configurations of the Internet terminal device 300 and the recording / reproducing device 1 will be described later.

The download-compatible disc 90A is an MD on which recording and reproduction are performed corresponding to the recording and reproduction apparatus 1.
As will be described later, this download-compatible disc 90A has a program area in which audio data is recorded and a URL (information source identification information) for specifying the Internet homepage 100.
Recording area (AUX-TOC1) where data is recorded, and a recording area (AUX data area) where data downloaded from the Internet homepage 100 is stored.
Is also set.

In this embodiment, the content of audio data recorded in the program area as information recorded on the download-compatible disc 90A and the URL are related. In other words, a URL that specifies a home page that provides information of the same attribute as the specific attribute as the content of the audio data is described. Specifically, assuming that the content of the audio data recorded in the program area is a song by an artist “A”, the URL may be, for example, a code designating an Internet homepage 100 that provides information on artist A. Is described. The logical disk structure of the download-compatible disk 90A will be described later.

An information collecting form by such an information collecting system will be briefly described. First, the user loads the recording / reproducing apparatus 1 with the download-compatible disc 90A owned by the user. Then, it is assumed that an operation for instructing the start of download is performed. In response to this operation, for example, the recording / reproducing apparatus 1 reads out the URL stored in the loaded download-compatible disc 90A and transmits it to the Internet terminal apparatus 300. In the Internet terminal device 300, the received UR
Internet homepage 100 specified by L
To access.

As described above, the URL recorded on the download-compatible disc 90A designates a page that provides information of the same attribute as a specific attribute as the content of the audio data. Therefore, assuming that this attribute corresponds to artist A, the Internet homepage 100 accessed here
Is a home page that provides various information related to artist A.

As described above, when accessing the Internet homepage 100 specified by the URL, the Internet terminal device 300 downloads the information provided on the Internet homepage 100 and sends it to the recording / reproducing apparatus 1. Transmit download data. In the recording / reproducing apparatus 1, the transmitted download data is recorded in a predetermined area (AUX data area) of the currently loaded download-compatible disc 90A.

As described above, in addition to audio data as main information, download information relating to the contents (attributes) of the audio data is also stored in the download-compatible disk 90A as data that can be reproduced and used by the user. It will be recorded as information.

In the recording / reproducing apparatus 1 according to the present embodiment, for the data recorded on the download-compatible disc 90A, the reproduction output of the audio data recorded in the program area and the reproduction of the download data recorded in the AUX data area are performed. Playback output can be performed. That is, in the present embodiment, it is possible to record and reproduce both audio data having a common attribute and data downloaded from the Internet on one download-compatible disc 90A.

The following can be considered as the form of the infrastructure of the information collection system having the configuration shown in FIG. One is to sell a downloadable disc 90A in which audio data such as music and a URL are recorded in advance. And
The company that sells the download-compatible disk 90A creates and issues an Internet homepage 100 specified by the URL. In this case, for example, if the user purchases a downloadable disc 90A on which music (audio data) of the artist A is recorded, inserts the disc into the recording / reproducing apparatus 1, and performs a required operation, For example, information downloaded from the Internet homepage 100 of the artist A prepared by the company can be recorded on the download-compatible disc 90A. That is, it is possible to acquire information related to the contents of the main data of the download-compatible disc 90A in a very simple manner.

The other is to leave a blank disc at the time of purchase so that the user can arbitrarily record audio data and URL. In this case, for example, the user himself / herself can record the music (audio data) of the artist A, and also record the URL of the Internet homepage 100 relating to the artist A found by the user himself. In this case, information related to the artist A can be collected from the homepage selected by the user himself, and the value as an original disc created by the user himself is enhanced. Also. As a modification, audio data is recorded at the time of purchase, and the URL can be arbitrarily recorded by the user.

Operators required for operation are provided. Operation information from these operation keys and dials is supplied to the system controller 11, and the system controller 11 executes operation control according to the operation information.

The display operation of the display unit 24 is controlled by the system controller 11. That is, the system controller 11 transmits data to be displayed when the display operation is performed to the display driver in the display unit 24. The display driver drives a display operation of a display by a liquid crystal panel or the like based on the supplied data, and executes display of required numbers, characters, symbols, and the like. The display unit 24 shows the operation mode state of the recording / reproducing disc, the track number, the recording time / reproduction time, the editing operation state, and the like. The disk 90 can record character information (track name and the like) managed in association with a program as main data. Display of input characters at the time of inputting the character information and display of character information read from the disk can be performed. And so on.

As a recording track in the mini disc system, clusters CL are continuously formed as shown in FIG. 5, and one cluster is a minimum unit for recording. One cluster corresponds to two or three tracks.

Then, one cluster CL includes the sector S
It is formed of a linking area of 4 sectors FC to SFF and a main data area of 32 sectors indicated as sectors S00 to S1F. One sector is a data unit formed of 2352 bytes. Of the four sub data areas, the sector SFF is a sub data sector,
Although it can be used for information recording as sub-data, three sectors SFC to SFE are not used for data recording. On the other hand, recording of TOC data, audio data, AUX data, and the like is performed in a main data area for 32 sectors. The address is recorded for each sector.

The sectors are further subdivided into units called sound groups, and two sectors are divided into 11 sound groups. That is, as shown in the figure, the sound groups SG00 to SG0A are included in two consecutive sectors such as an even sector such as the sector S00 and an odd sector such as the sector S01. One sound group is formed of 424 bytes,
The amount of audio data is equivalent to 11.61 msec. In one sound group SG, data is recorded while being divided into an L channel and an R channel. For example, the sound group SG00 includes L channel data L0 and R channel data R0.
Is composed of L channel data L1 and R channel data R1. Note that 212 bytes, which is a data area of the L channel or the R channel, is called a sound frame.

5. Area Structure Next, the area structure of the download-compatible disc 90A of this example will be described with reference to FIG. FIG. 6A shows the area from the innermost side to the outermost side of the disk. The disk 90 as a magneto-optical disk has a pit area in which read-only data is formed by emboss pits on the innermost side, and a P-TOC is recorded here. The outer periphery of the pit area is a magneto-optical area, which is a recordable / reproducible area in which a groove is formed as a guide groove for a recording track. The innermost cluster 0 of this magneto-optical area
The section up to the cluster 49 is set as a management area, and a program such as an actual music program is recorded in the program area from the cluster 50 to the cluster 2251. The lead-out area is located outside the program area.

FIG. 6 shows the inside of the management area in detail.
(B). FIG. 6B shows sectors in the horizontal direction and clusters in the vertical direction. In the management area, clusters 0 and 1 are buffer areas with the pit area. The cluster 2 is a power calibration area PCA and is used for adjusting the output power of the laser beam. For clusters 3, 4, and 5, U-TOC is recorded. U
Although the contents of -TOC will be described later, a data format is defined in each sector in one cluster, and predetermined management information is recorded in each sector.
A cluster having a sector serving as C data is repeatedly recorded three times in clusters 3, 4, and 5.

Clusters 6, 7, and 8 are AUX-TOC areas in which AUX-TOC is recorded. AUX-TOC
As will be described later, the data format is defined in each sector in one cluster, and it is defined that predetermined management information is recorded.

C is a URL (Internet homepage 10
The sector in which the (0 address) is stored as a character code and the sector in which the update date and time of the file of the download data as AUX data are stored are also set. Clusters having a sector serving as such AUX-TOC data are repeatedly recorded three times in clusters 6, 7, and 8.

The area from the cluster 9 to the cluster 46 is an area where AUX data is recorded (AUX data area). In the download compatible disc 90A, A
Download data is recorded as UX data. Although a detailed description of the data structure in the AUX data is omitted, the download data recorded in the AUX data area is managed on a file basis by an AUX-TOC (area allocation table). Also, the download data recordable area in the AUX data area is managed by the AUX-TOC (area allocation table).

The recording capacity of the data file in the AUX data area is 2.8 Mbytes when considered as the error correction mode 2. Further, for example, it is conceivable to increase the recording capacity of the data file by forming a second AUX data area in the latter half of the program area or in an area on the outer periphery side of the program area (for example, a lead-out part).

The clusters 47, 48 and 49 are buffer areas for the program area. Cluster 50 (= 32

U-TOC 6-1 U-TOC sector 0 As described above, in order to perform the recording / reproducing operation of the program (track) on the disk 90 (including the download-compatible disk 90), the system controller 11 needs to The P-TOC and U-TOC as management information recorded on the disk 90 are read out and referred to when necessary. Here, the disk 90
The U-TOC sector will be described as management information for managing the recording / reproducing operation of a track (music or the like) in FIG. The U-TOC format includes a download compatible disc 90A and a general mini disc (disc 90) that does not support download data recording.
It is common with.

The P-TOC is formed in the innermost pit area of the disk 90 as described with reference to FIG. 6, and is read-only information. The P-TOC manages the position of a recordable area (recordable user area), a lead-out area, a U-TOC area, and the like on the disc. In a read-only optical disk in which all data is recorded in a pit form,
The P-TOC can also manage music recorded in the form of a ROM and the U-TOC is not formed. A detailed description of the P-TOC is omitted, and here, the U-
-TOC will be described.

FIG. 7 shows the format of U-TOC sector 0. The U-TOC sector can be provided from sector 0 to sector 32, in which sector 1 and sector 4 are character information, and sector 2 is an area for recording the recording date and time. First, U which is always necessary for the recording / reproducing operation of the disc 90
-TOC sector 0 will be described.

The U-TOC sector 0 is a data area in which management information on a program such as a song recorded by a user and a free area in which a new program can be recorded is mainly recorded. For example, when attempting to record a certain music on the disk 90, the system controller 11 searches for a free area on the disk from the U-TOC sector 0, and records audio data there. At the time of reproduction, the area in which the music to be reproduced is recorded is determined from U-TOC sector 0, and the reproduction operation is performed by accessing the area.

The data area (4 bytes × 588, 2352 bytes) of the U-TOC sector 0 has all 0s at the head position.
Alternatively, a synchronization pattern in which all 1-byte data are formed side by side is recorded. Then the cluster address (Clust
er H) (Cluster L) and an address serving as a sector address (Sector) are recorded over 3 bytes, and one byte of mode information (MODE) is added. The 3-byte address here is the address of the sector itself.

The header portion in which the synchronization pattern and the address are recorded is not limited to the U-TOC sector 0, but may be a P-TOC sector, an AUX-TOC sector, or an A-TOC sector.
The same applies to the UX file sector and the program sector. For each of the sectors shown in FIG. 9 and thereafter, the description of the header portion is omitted, but the address and synchronization pattern of the sector itself are recorded in sector units. In addition, as the address of the sector itself, the cluster address includes an upper address (Cluster H) and a lower address (Cluster H).
L), and the sector address (Sector) is written in 1 byte. That is, this address is not in short form.

Subsequently, a maker code, a model code, and a track number (F
irst TNO), track number of last track (Last T
NO), data such as sector usage (Used sectors), disk serial number, and disk ID are recorded.

Further, various pointers (P-DFA) are used as pointers in order to identify the areas (free areas, etc.) of tracks (music and the like) recorded by the user by making them correspond to a table section described later. , P-EMPT
An area for recording Y, P-FRA, and P-TNO1 to P-TNO255) is prepared.

The table part to be associated with the pointers (P-DFA to P-TNO255) is (01h) to (FFh) (in this specification, the number with “h” is the value in hexadecimal notation. 255) are provided, and in each part table, a start address as a starting point, an end address as an end, and mode information (track mode) of the part are recorded. . Furthermore, since parts indicated in each part table may be successively connected to other parts, link information indicating a part table in which a start address and an end address of the connected part are recorded can be recorded. Have been. Note that a part refers to a track portion in which temporally continuous data is physically continuously recorded in one track. The addresses indicated as the start address and the end address are addresses indicating one or a plurality of parts constituting one music piece (track). These addresses are recorded in short form and specify clusters, sectors, and sound groups.

In this type of recording / reproducing apparatus, data of one music (program / track) is reproduced in a physically discontinuous manner, that is, while data is recorded over a plurality of parts, while accessing between parts. Therefore, there is a case where a music piece or the like recorded by a user is divided into a plurality of parts for the purpose of efficient use of a recordable area.

For this purpose, link information is provided, and the part tables can be connected by designating the part tables to be connected, for example, by the numbers (01h) to (FFh) given to the respective part tables.
In other words, in the management table section in the U-TOC sector 0, one parts table represents one part. For example, for a music composed of three parts connected, three parts connected by link information The position of the part is managed by the table. Note that the link information is actually indicated by a numerical value which is a byte position in the U-TOC sector 0 by a predetermined arithmetic processing. That is, the part table is designated as 304+ (link information) × 8 (byte).

Each part table from (01h) to (FFh) in the table section of the U-TOC sector 0 includes pointers (P-DFA, P-EMPTY, P-FRA, P-TNO1) in the pointer section.
~ P-TNO255) indicates the contents of the part as follows.

The pointer P-DFA is attached to a defective area on the magneto-optical disk 90. The pointer P-DFA is located in a single part table or a plurality of parts tables showing a track portion (= part) serving as a defective area due to a scratch or the like. Of the first part table is specified. That is, when a defective part exists, any one of (01h) to (FFh) is recorded in the pointer P-DFA, and the corresponding part table indicates the defective part by the start and end addresses. If another defective part exists, another part table is designated as link information in the part table, and the defective part is also indicated in the part table. If there is no other defective part, the link information is set to, for example, "(00h)".
After that, there is no link.

The pointer P-EMPTY indicates the head part table of one or a plurality of unused part tables in the management table section. If an unused part table exists, the pointer P-EMPTY is set as (P-EMPTY). 01h)-(F
Fh) is recorded. When there are multiple unused part tables, the part tables are sequentially specified by the link information from the part table specified by the pointer P-EMPTY, and all the unused part tables are linked on the management table section. You.

The pointer P-FRA indicates a free area (including an erase area) where data can be written on the magneto-optical disk 90, and one or a plurality of track portions (= parts) indicating the free area are indicated. The first part table in the parts table is specified. In other words, if there is a free area, (01
h) to (FFh) are recorded, and in the corresponding parts table, parts which are free areas are indicated by start and end addresses. Further, when there are a plurality of such parts, that is, when there are a plurality of parts tables, the link information sequentially designates parts tables whose link information is "(00h)".

FIG. 8 schematically shows the management state of parts that are free areas by using a parts table. This is because when the parts (03h) (18h) (1Fh) (2Bh) (E3h) are set as free areas, this state follows the pointer P-FRA and the parts table (03h) (18h) (1Fh) (2Bh) The state represented by the link (E3h) is shown. The above-described management of the defective area and the unused parts table is the same.

The pointers P-TNO1 to P-TNO255 indicate tracks such as tunes recorded by the user on the magneto-optical disk 90. For example, the pointer P-TNO1 indicates the first track.
A part table indicating a temporally leading part of one or a plurality of parts in which track data is recorded is designated. For example, if the music piece set as the first track (first program) is recorded on the disk without dividing the track, that is, as one part, the recording area of the first track is indicated by the pointer P-TNO1. Are recorded as start and end addresses in the parts table.

For example, in the case where the music set as the second track (second program) is discretely recorded on a plurality of parts on the disc, each part is time-based to indicate the recording position of the second track. Are specified according to a typical order. In other words, from the part table designated by the pointer P-TNO2, another part table is sequentially designated by the link information in order of time, and linked to the parts table in which the link information is "(00h)" ( The above-described embodiment is similar to that of FIG. 8). In this way, for example, since all the parts on which the data constituting the second tune are recorded are sequentially designated and recorded, the data of the U-TOC sector 0 can be used to reproduce the second tune or the second tune. When performing overwrite recording on the area, it is possible to access the optical head 3 and the magnetic head 6a to extract continuous music information from discrete parts, and to perform recording using the recording area efficiently.

As described above, for the rewritable magneto-optical disk 90, the area management on the disk is performed by the P-TOC.
The music and free areas recorded in the recordable user area are performed by U-TOC.

6-2 U-TOC Sector 1 FIG. 9 shows the format of U-TOC sector 1. The sector 1 is used as a data area for recording input character information when a track name is given to each recorded track or a disc name is used as information such as the name of the disc itself.

The U-TOC sector 1 has a pointer P-TN as a pointer portion corresponding to each recorded track.
A1 to P-TNA255 are prepared, and the pointers P-TNA1 to P-TNA255
The slot part specified by TNA255 is 8 bytes in one unit, and slots (01h) to (FFh) of 255 units and one slot (00h) of 8 bytes are prepared. Character data is managed in a similar manner.

In the slots (01h) to (FFh), character information as a disc title or a track name is recorded in ASCII code. Then, for example, a character input by the user corresponding to the first track is recorded in the slot specified by the pointer P-TNA1. Further, by linking the slots by the link information, the character input corresponding to one track can be handled even if it is larger than 7 bytes (7 characters). Note that 8 bytes as the slot (00h) are a dedicated area for recording a disc name, and are not specified by the pointer P-TNA (x). This U-TOC sector 1
But the pointer P-EMPTY manages unused slots.

6-3 U-TOC Sector 2 FIG. 10 shows a format of the U-TOC sector 2, and this sector 2 is mainly used as a data area for recording a recording date and time of a music piece recorded by a user. You.

The U-TOC sector 2 has a pointer P-TR as a pointer corresponding to each recorded track.
D1 to P-TRD255 are prepared, and the pointers P-TRD1 to P-TRD255
A slot specified by TRD255 is prepared. In the slot part, one unit is 8 bytes and a slot of 255 units (0
1h) to (FFh) are formed, and the date and time data is managed in substantially the same form as that of the U-TOC sector 0 described above.

In the slots (01h) to (FFh), the recording date and time of the music (track) are recorded in 6 bytes. Six bytes record numerical values corresponding to year, month, day, hour, minute, and second, one byte at a time. The remaining two bytes are a maker code and a model code, in which code data indicating the manufacturer of the recording device that recorded the music and code data indicating the model of the recording device that recorded the music are recorded.

For example, when a track is recorded as the first music piece on a disc, the recording date and time, the maker code and model code of the recording device are recorded in the slot specified by the pointer P-TRD1. The recording date and time data is automatically recorded by the system controller 11 with reference to the internal clock.

Eight bytes as the slot (00h) are a dedicated area for recording the recording date and time in disk units, and are slots not specified by the pointer P-TRD (x). In this U-TOC sector 2, the slot pointer P-EMPTY manages unused slots. For unused slots, link information is recorded in place of the model code, and each unused slot is managed by linking with the link information starting from the slot pointer P-EMPTY.

6-4 U-TOC Sector 4 FIG. 11 shows the U-TOC sector 4, and this sector 4
, Like the sector 1 described above, give the song name (track name) to the track on which the user has recorded,
When a disc name is given, the data area is used as a data area for recording the input character information. As can be seen by comparing FIGS. 11 and 9, the format is almost the same as that of the sector 1. However, this sector 4 is designed to record code data (two-byte code) corresponding to kanji and European characters. In addition to the data of sector 1 in FIG. Is recorded.
The management of the character information of the U-TOC sector 4 is performed by the pointers P-TNA1 to P-TNA255 and the pointer P-TNA255 similarly to the sector 1.
This is performed by slots (01h) to (FFh) of 255 units specified by TNA1 to P-TNA255.

Although the recording / reproducing apparatus 1 of this embodiment can deal with a read-only disc in which a U-TOC is not formed, in the case of a read-only disc, character information as a disc name and a track name is recorded in the P-TOC. I can put it. That is, U as a P-TOC sector
Sectors substantially similar to the -TOC sector 1 and the sector 4 are prepared, and the disc maker can record the disc name and the track name in the P-TOC sector in advance.

7. AUX-TOC 7-1 AUX-TOC sector 0 In the disc 90 of the present example, the AUX
An area for recording the data file and the AUX-TOC is set, and character information and image information independent of tracks (programs) such as music can be recorded as the AUX data file. And download compatible disc 90A
Is a file in which download data is recorded as an AUX data file. This AUX data file is managed by AUX-TOC. The AUX-TOC is repeatedly recorded three times over three clusters. Therefore, the management data structure is a U-TOC.
Like C, 32 sectors in one cluster can be used. In the download-compatible disk 90A of this example, as described below, AUX-TOC sector 0 is set to manage the AUX data file. Also, AUX-T
The URL is recorded as a character code for the OC sector 1 and the update date and time of the file of the download data is recorded for the AUX-TOC sector 2.

The following description of the AUX-TOC is based on the premise that one URL is stored in the download-compatible disk 90A.
That is, as the AUX data file, one Internet homepage 10 specified by the above URL is used.
The information provided by 0 is stored.

First, the format of AUX-TOC sector 0 will be described with reference to FIG. AUX-T
The OC sector 0 is an area allocation table that manages the entire AUX data area, and manages download data recorded in the AUX data area.
Here, the download data, that is, the data of the homepage is usually formed by a plurality of hierarchical pages.
Each page is composed of one or a plurality of file data (hereinafter also referred to as a homepage file). In this embodiment, the download data recorded in the AUX data area is indicated by AUX-TOC sector 0.
It is assumed that the data is managed in units of files forming the data of the homepage.

As shown in FIG. 12, this sector 0
Then, a maker code, a model code, backup information, and used sector information are recorded at predetermined byte positions following the header. Used sector information includes AU
The sector usage in the X-TOC is shown.

In the AUX-TOC sector 0, pointers P-FNO1 to P-FNO255 are formed as pointer portions following the pointers P-DFAA and P-EMPTY. Then, in the table section, 255-unit parts tables each of 8 bytes in which a start address, an end address, and link information are recorded are formed, and the AUX data area is managed in the same manner as in the U-TOC sector 0 described above.

In this case, the pointers P-FNO1 to P-FNO255
Manages an area in the AUX data area in which one homepage file is recorded by designating a specific parts table. Eg pointer
In the parts table specified by P-FNO1, for example, the start address and end address of the part in which the head data part is recorded among one or a plurality of parts in which the homepage file with the youngest file number is recorded are recorded. The state is recorded.

The pointer P-DFAA manages a defective area in the AUX data area by using a start address and an end address recorded in a designated parts table. If there are a plurality of defective areas, another parts table is linked by the link information. The pointer P-EMPTY is
Unused part tables in the OC sector 0 are managed in a link form.

The pointer P-BLANK indicates a free area in the AUX data area, that is, an area in which the AUX data file can be recorded, in the U-TOC sector 0.
Is managed in the form of a link in the parts table, similarly to the pointer P-FRA in.

7-2 AUX-TOC Sector 1 FIG. 13 shows the format of AUX-TOC sector 1. The sector 1 is a URL table, and is an area in which a URL, which is an address code for accessing the Internet homepage 100, is recorded by a character code.

In the AUX-TOC sector 1, a pointer P-EMPTY is set in the pointer section.
Unused part tables in the OC sector 0 are managed in a link form. In the slot section, slots (01h) to (FFh) of 255 units in units of 8 bytes and one slot (00h) of 8 bytes are prepared.

In the slots (00h) to (FFh), character information as a URL is recorded in ASCII codes or other character codes. The type of the recorded character is recorded at a predetermined byte position as a character code. The character code is, for example, "0
0h ”is an ASCII code, and“ 01h ”is a modified ISO. 8859-1 and "02h" are set as in Music Shifted JIS.

Here, it is assumed that one URL is stored in one download-compatible disk 90A as described above. The character information as the URL is
It is assumed that the data is always recorded from the first byte of the slot (00h) in the slot section.

7-3 AUX-TOC Sector 2 FIG. 14 shows the format of AUX-TOC sector 2. The sector 3 is a file update date / time table, and is a data area for managing the update date / time of each recorded homepage file. The update date and time referred to here is the last date and time when the content of the homepage recorded in the AUX data area was rewritten and recorded. Are different.

In this AUX-TOC sector 2, pointers P-FRD1 to P-FRD255 are used as pointers corresponding to the update date and time of each homepage file recorded in the slot.
Are prepared, and a slot portion designated by the pointers P-FRD1 to P-FRD255 is prepared. The slot part is 8 bytes per unit and 255 units of slots (01h) to (FFh)
Also, one slot (00h) of 8 bytes is formed, and manages the date and time data in substantially the same manner as the U-TOC sector 2 described above.

In the slots (01h) to (FFh), the update date and time of each homepage file is recorded using 8 bytes. With a capacity of 8 bytes, it is possible to record numerical values corresponding to year, month, day, hour, minute, and second.

For example, in the AUX data area, when the contents of the homepage file of the first file number are updated and recorded (or when the contents are first recorded),
The date and time of the update is recorded in the slot specified by the pointer P-FRD1. The recording date and time data may be automatically recorded by the system controller 11 with reference to the internal clock.

The above-described management mode using AUX-TOC is merely an example. Here, the description has been made on the assumption that only the download data is recorded in the AUX data area. However, for example, in the case where a configuration in which data other than the download data can be recorded in the AUX data area is adopted, First, the AUX-TOC sector 0 manages the recording area for each prescribed data type, and the remaining specific AUX
A mode may be adopted in which management is performed for each type of data by the TOC sector.

Further, for example, it is possible to store a plurality of URLs. In this case, in the AUX-TOC sector as the URL table shown in FIG. And the URL may be recorded for each of the slots specified by the pointer. At this time, when the description of the URL extends over a plurality of slots, the link destination slot may be indicated by the link information.

8. Recording of Download Data Subsequently, the recording operation of the download data by the recording and reproducing apparatus 1 using the information collection system of the present embodiment will be described with reference to the flowchart of FIG. In this figure,
The processing on the recording / reproducing apparatus 1 side shown in steps S101 to S108 and the processing on the Internet terminal apparatus 300 side shown in steps S201 to S208 are shown in parallel. The processing on the recording / reproducing apparatus 1 side is executed by the system controller 11 and the Internet terminal 30
The process on the 0 side is executed by the communication controller 34.

Here, first, the system controller 1
As a process 1, in step S101, the process waits for the download-compatible disc 90A to be loaded into the recording / reproducing apparatus 1. If it is determined that the download-compatible disk 90A has been loaded, the process proceeds to step S102, where the download-compatible disk 90A is loaded.
AUX-UTOC data is read from the management area. That is, the AUX- shown in FIGS.
The data contents of the UTOC sectors 0 to 2 are read. This read AUX-UTOC sector 0
Are stored in a predetermined area of the buffer memory 13, for example, as described above.

Subsequently, the system controller 11 executes the processing of step S103, in which the URL data stored in the AUX-UTOC sector 1 and the AUX-U
The data of the update date and time of each homepage file stored in the TOC sector 2 is transmitted and output to the Internet terminal device 300 via the interface 25.

During this time, the communication controller 34 of the Internet terminal device 300 transmits the UR transmitted from the recording / reproducing device 1 as shown in the processing of step S201.
L and waiting for the update date and time data of the homepage file to be received. When it is determined that these data have been received, the process proceeds to step S202,
The URL and the update date and time data of the homepage file are stored and held in the RAM 35, for example.

In the following step S203, the Internet homepage 100 specified by the received URL
Execute control to access. That is, as described above, the communication unit 31 controls the connection to the Internet homepage 100.

When the Internet homepage 100 is accessed by the processing in step S203, the communication controller 34 proceeds to step S204,
For each homepage file provided on the Internet homepage 100, it is determined whether or not there is a homepage file whose contents have been updated.

In the process of step S204, the communication controller 34 determines whether the contents of the update date and time data (contents of the AUX-UTOC sector 2) of the homepage file held in the RAM 35 and the Internet homepage 10
The home page file provided on the 0 side is compared with the update date and time information.

Then, with respect to the update date and time of the homepage file as the contents of the AUX-UTOC sector 2,
If there is a new homepage file with the updated date and time of the homepage file provided on the Internet homepage 100, it is determined that a homepage file with updated data content exists. On the other hand, if there is no newer homepage file in the homepage file provided on the Internet homepage 100 than in the homepage file as the content of the AUX-UTOC sector 2, the data is updated. It is determined that the homepage file whose contents have been updated does not exist.

If a positive result is obtained by the determination processing in step S204 as described above, the communication controller 34 determines in step S205 that the download data (that is, the homepage file whose contents have been updated) is obtained.
Is transmitted to the system controller 11 on the recording / reproducing apparatus 1 side.

Then, in a succeeding step S206,
From the homepage file provided as the Internet homepage 100, the previous step S2
04, the homepage file determined to have been updated based on the content of the homepage is accessed, received and temporarily stored in the RAM 35, and a control process for transmitting the data of the captured homepage file to the recording / reproducing apparatus 1 is performed. Execute. At this time, if necessary, the receiving decoder 32 also executes control for performing processing so that the data format of the received homepage file becomes a format that can be processed by the recording / reproducing apparatus 1 side. You.

In step S207, the process waits for the end of the transfer of the download data started in step S206, and ends the process of this routine when the transfer is completed.

If a negative result is obtained in step S204 (if it is determined that there is no homepage file whose contents have been updated), the process proceeds to step S208, and information notifying that download data is not transferred is provided. Is transmitted to the system controller 11 on the recording / reproducing apparatus 1 side, and the processing of this routine ends.

On the other hand, in step S104, the system controller 11 of the recording / reproducing apparatus 1 waits for notification information indicating whether there is download data transmitted from the Internet terminal apparatus 300 side. Here, when the notification information indicating that the download data is transferred is received by executing the processing of step S205 described above, the system controller 11 determines that there is download data, and proceeds to step S105. move on.

In step S105, the download data transmitted from the Internet terminal device 300, that is, the data of the homepage file to be updated is fetched via the interface 25. The fetched download data is stored in the buffer memory 13 under the control of the system controller 11. In addition, if necessary information is obtained from information obtained along with the download data, the system controller 11 extracts and extracts the information and stores the extracted information in a predetermined area on the buffer memory 13.

As described above, the system controller 1
The data accumulated in the buffer memory 13 under the control of 1 is recorded in the AUX data area of the download-compatible disc 90A by the process of step S106. At this time, the system controller 11
, Sequentially reads out download data stored in the buffer memory 13 and supplies the read data to the encoder / decoder unit 8. Then, necessary recording operation control is executed so that the download data encoded by the encoder / decoder unit 8 is recorded in the AUX data area.

After the processing in step S106, the system controller 11 waits in step S107 for the recording of the transferred download data to be completed. When the recording is completed, the system controller 11 proceeds to step S107.
Proceed to 108.

In step S108, a process for updating the contents of the AUX-TOC area in accordance with the result of the recording performed so far is executed, and this process ends. At this time, first, the data content of the AUX-TOC held in the buffer memory 13 is rewritten (updated), and the updated AUX-TOC data on the buffer memory 13 is
The data is written in the AUX-TOC area of the download-compatible disc 90A. At this time, for example, AU
When the homepage file of the Internet homepage 100 is recorded in the X data area, the homepage file having the same file number as the newly recorded homepage file among the homepage files previously recorded is newly added. The recorded homepage file is managed as overwritten and erased.

In step S104, the processing in step S208 described above is executed,
When the notification information indicating that the download data is not transferred is received, the system controller 11 determines that there is no download data, and ends this processing as it is.

As described above, in the present embodiment, information is downloaded using the URL stored in the download-compatible disk 90A, and the downloaded information is recorded on the same download-compatible disk 90A. To be. According to the processing shown in FIG. 15, for each access to the Internet homepage, only the homepage file having an update date and time that is newer than the update date and time recorded on the downloadable disk 90A is downloaded and the downloadable disk 90A is downloaded. However, this is designed to reduce the download time and to efficiently collect download data.

9. Modifications of Information Collection System 9-1 Modification 1 Next, various modifications of the information collection system according to the present embodiment will be described with reference to FIGS.
In these drawings, the same parts as those in FIGS. 1 and 2 are denoted by the same reference numerals, and description thereof will be omitted.

FIG. 16 shows an information collection system as a first modification. In this case, a configuration is adopted in which game data provided on the Internet homepage 100 is also downloaded as download data as homepage file data, and can be recorded on the download-compatible disc 90A.

In this configuration, description of the internal configuration and the like is omitted, but, for example, the Internet terminal device 300 is configured to function as a game device. For this reason,
As shown in the figure, the Internet terminal device 300 is provided with a joystick, a keyboard, and the like, and an operation unit 700 for a user to operate when playing a game.
Is connected. In addition, the Internet terminal device 300 is also provided with a video signal processing circuit system for outputting a game image to the monitor device 500.

In order for the user to play a game using this system, the game program downloaded from the Internet homepage 100 is recorded in the AUX data area on the downloadable disc 90A in advance, as described above. To keep.
Then, when actually playing the game, the recording / reproducing device 1
Reads the game program recorded in the AUX data area by the
To the RAM 35. Internet terminal device 30
0, the transmitted game program is stored in the RAM 3
5 and activated to execute the game program. At this time, the game image is displayed and output on the monitor device 500 by the video information output from the Internet terminal device 300. The user plays the game by operating the operation unit 700 while the game program is being executed in this manner.

9-2 Modification 2 FIG. 17 shows a configuration of an information collection system as Modification 2. In this case, a system configuration including a portable recording / reproducing apparatus 1A instead of the recording / reproducing apparatus 1 is shown. For example, the recording / reproducing apparatus 1 described so far
Is a so-called stationary type, the portable recording and reproducing apparatus 1A is configured to be smaller and lighter, for example.
Battery operation is also possible and portability is provided.

In such a system configuration, as shown in FIG. 1 and FIG. 2, in addition to the form of the infrastructure in which the Internet terminal device 300 and the portable recording / reproducing device 1A are owned by the user, For example, it is conceivable that the Internet terminal device 300 is installed in a store such as a convenience store and the user owns the portable recording and reproducing device 1A. . Then, the user enters the Internet terminal device 300
Is installed, the portable recording / reproducing apparatus 1A owned by the user is connected to the Internet terminal apparatus 300, and the download data is recorded on the download-compatible disk 90A and obtained.
