Description

  The present invention relates to a data recording / reproducing apparatus, a data recording method, and a program.

  Instead of a device that records music and other data on a disk-shaped recording medium such as a CD (Compact Disk), recently, a large-sized card such as an SD memory card (Secure Digital memory card) has been developed due to the increased capacity of flash memory. An apparatus for recording data such as music using a capacity recording medium has become widespread. For example, Patent Document 1 discloses an apparatus capable of reproducing both a disk-shaped recording medium and a card-shaped recording medium. In addition to a card-like recording medium, a removable recording medium such as a recording medium called a USB memory that can be attached to and detached from a USB (Universal Serial Bus) port has become widespread. Hereinafter, these recording media are referred to as non-disc recording media.

  Such a non-disc recording medium is extremely compact compared to a disc-shaped recording medium such as a CD. Therefore, the non-disk recording medium has the convenience of being able to carry a large number of data easily compared to the disk-shaped recording medium. Further, an apparatus for reading information from a disk-shaped recording medium includes many mechanical drive parts such as rotating the disk and moving a pickup. On the other hand, an apparatus for reading information from a non-disk recording medium does not include a mechanical drive portion. Therefore, the device itself is resistant to vibrations and shocks when it is carried, and there is no problem in reading data due to vibrations and shocks. Due to such advantages, recording / reproducing apparatuses using non-disc recording media are rapidly spreading.

(First embodiment)
A data recording / reproducing apparatus 1 according to a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is an external view of the data recording / reproducing apparatus 1. FIG. 2 is a block diagram of the data recording / reproducing apparatus 1. Below, the card-shaped recording medium 2 is illustrated as a non-disk recording medium. The data recording / reproducing apparatus 1 will be described as an apparatus for recording and reproducing music data. The details of the reproduction of the music data are not described here.

As shown in FIG. 1, the data recording / reproducing apparatus 1 has one insertion slot 3 into which a recording medium 2 is inserted. Further, the housing of the data recording / reproducing apparatus 1 includes a display unit 4 and an operation unit 5. As shown in FIG. 2, the data recording / reproducing apparatus 1 that records data on the recording medium 2 is designation information writing means for writing designation information that designates the type of data to be recorded on the recording medium 2 into the recording medium 2. The specified information writing unit 6, the data type identifying unit 7 as data type identifying means for identifying the type of data to be recorded, and whether the specified information matches the data type identified by the data type identifying unit 7 A data type confirming unit 8 as data type confirming means for confirming whether or not, and a data recording unit 9. The data recording unit 9 includes data recording means for recording data on the recording medium 2 when the data type confirming unit 8 confirms that the designation information matches the data type identified by the data type identifying unit 7. Become.
Here, all or a part of the designation information writing unit 6, the data type identification unit 7, the data type confirmation unit 8, and the data recording unit 9 seems to be handled by a program installed in a CPU (Central Processing Unit) and a memory. However, each function may be realized by other hardware or other circuit elements. Further, the designation information writing unit 6, the data type identification unit 7, the data type confirmation unit 8, and the data recording unit 9 together serve as a control unit.

  In addition, as shown in FIG. 1, the data recording apparatus 1 includes a CD insertion slot 10 in the housing of the data recording / reproducing apparatus 1. As shown in FIG. 2, the data recording apparatus 1 includes a CD playback function unit 11, a tuner playback function unit 12, a network communication function unit 13, an HDD (Hard Disk Drive) 14, and the like. In addition, illustration of members, such as an antenna and a cable connection terminal required for the tuner reproduction | regeneration function part 12, the network communication function part 13, etc., ie, members other than main structures, is abbreviate | omitted. The CD playback function unit 11 plays back the CD inserted from the CD insertion slot 10 and outputs data. The tuner reproduction function unit 12 receives FM (Frequency Modulation) broadcast and the like and outputs data. The network communication function unit 13 receives and outputs data distributed via a network such as the Internet. The HDD 14 records data output from the CD playback function unit 11, tuner playback function unit 12, and network communication function unit 13. Note that the HDD 14 can hold metadata included in data to be recorded as content data. Alternatively, the HDD 14 can generate metadata based on the data to be recorded and hold it as content data.

  The function of the CD playback function unit 11 is achieved by a CD playback device and a CPU, and the function of the tuner playback function unit 12 is achieved by a tuner device and a CPU. The function of the network communication function unit 13 is achieved by a cable connecting each device, a communication device, a CPU, and the like. A DSP (Digital Signal Processor) or the like can be used instead of the CPU.

  The user can write the designation information to the recording medium 2 by operating the designation information writing unit 6 with the operation unit 5. This designation information is information that is designated based on the metadata that the data has or the media type that is the data transfer source.

For example, the data recording unit 9 reads data from the CD playback function unit 11 and MP3 (MPEG
When converting into compressed data such as Audio Layer-3) and recording on the recording medium 2, recording is performed on the recording medium 2 in which the media type of the designated information is designated as “CD”. Similarly, when the data recording unit 9 reads the data received by the tuner playback function unit 12 and records it on the recording medium 2, the data recording unit 9 records the data on the recording medium 2 in which the media type of the designated information is designated as “tuner”. Alternatively, when the data recording unit 9 reads the data distributed by the music distribution service via the Internet from the network communication function unit 13 and records it on the recording medium 2, the media type of the designation information is designated as “music distribution service” To the recorded recording medium 2.

  The data type identification unit 7 determines the media type. For example, the data type identification unit 7 is data output from any output port (not shown) of the CD playback function unit 11, tuner playback function unit 12, network communication function unit 13, or HDD 14, each serving as a data source. By monitoring whether the data exists, the media type of the data can be determined.

  Further, when the data to be recorded has metadata, information specified based on the metadata can be designated information. Data having metadata is, for example, content data in the HDD 14. In the content data of the HDD 14, genre, age, artist name, etc. are recorded as metadata. The designation information based on these metadata can be written to the recording medium 2. Thus, the recording medium 2 can be prevented from recording data that does not match the specified information.

  The designation information may not be single. For example, it is possible to specify by a combination such that the media type of the designation information is “CD”, the genre designation is “Jazz”, and the age designation is “1960s”. Moreover, although the combination example of said designation | designated information is "CD" AND "Jazz" AND "1960s", this is good also as "CD" OR "Jazz" OR "1960s". The user designates these combination methods from the operation unit 5.

  The data type identification unit 7 or the data recording unit 9 includes a temporary storage unit such as a buffer (not shown). The reason will be described below. That is, after the data type identification unit 7 identifies the data type of the data to be recorded, the data type confirmation unit 8 compares the specified information with the data type, and then the data recording unit 9 actually records the data on the recording medium 2. Record data. Therefore, there is a time lag between when the recording target data is output from the CD playback function unit 11, the tuner playback function unit 12, the network communication function unit 13, and the HDD 14 until the recording of the recording target data is actually started. Sometimes. This is because a temporary storage unit such as a buffer is often required to absorb this time lag. However, if a method such as speeding up the processing or temporarily recording all the data and then performing the above-described processing and deleting unnecessary data is temporarily stored in the data type identification unit 7 or the data recording unit 9. Department is not required.

  The data recording / reproducing apparatus 1 has one insertion port 3 for the recording medium 2. The user inserts a different recording medium 2 into the insertion slot 3 when the designation information of the recording medium 2 initially inserted into the insertion slot 3 does not match the data type of the data to be recorded designated by the user. In this way, finally, the recording medium 2 in which the designation information of the recording medium 2 inserted into the insertion slot 3 matches the data type of the data to be recorded designated by the user is found. At this time, the data recording / reproducing apparatus 1 is different from the conventional one in that the user does not need to confirm detailed information displayed on the display unit 4. That is, it is determined by the data type identification unit 7 and the data type confirmation unit 8 whether the designation information of the recording medium 2 inserted into the insertion slot 3 matches the data type of the data designated by the user. For this reason, when this data recording / reproducing apparatus 1 is used, a user's direct judgment becomes unnecessary and the convenience of a user improves compared with the past.

  Here, the operation of the data type confirmation unit 8 will be described with reference to the flowchart of FIG. FIG. 3 is a flowchart showing an operation procedure of the data type confirmation unit 8. As shown in FIG. 3, when the data type confirmation unit 8 confirms the insertion of the recording medium 2 into the insertion slot 3 (step S1), the data type confirmation unit 8 determines the presence / absence of the designation information written in the recording medium 2 (step S2). ). When the designation information is written in the recording medium 2 (Yes in step S2), the data type confirmation unit 8 reads the designation information (step S3). Further, the data type confirmation unit 8 confirms the data type of the recording target data identified by the data type identification unit 7 (step S4). The data type confirmation unit 8 compares the designation information read in step S3 with the data type confirmed in step S4 (step S5). If the designation information read in step S3 matches the data type confirmed in step S4, the data type confirmation unit 8 instructs the data recording unit 9 to start recording data (step S7).

  If the designation information read in step S3 and the data type confirmed in step S4 do not match (No in step S6), the data type confirmation unit 8 displays a designation information mismatch on the display unit 5 (step S8). The user removes the recording medium 2 from the insertion slot 3 when “designated information mismatch” is displayed on the display unit 5, and inserts another recording medium 2 into the insertion slot 3.

  The data type confirmation unit 8 determines that the designation information for the recording medium 2 is stored in the designation information writing unit 6 when the designation information is not written in the recording medium 2 in the determination in step S2 (No in step S2). Is instructed to write (step S9). The designation information writing unit 6 executes the process shown in FIG. 4 in accordance with an instruction from the data type confirmation unit 8. FIG. 4 is a flowchart showing the procedure of the designation information writing process in the designation information writing unit 6. Note that after the designation information is written to the recording medium 2 by the designation information write instruction in step S9, the process proceeds to the designation information reading instruction in step S3.

  As shown in FIG. 4, if the data type of the recording target data has been identified by the data type identification unit 7 (Yes in step S10), the designation information writing unit 6 generates designation information for the identified data type. Then, it is written in a predetermined storage area of the recording medium 2 (step S11). In addition, if the data type of the data to be recorded has not yet been identified by the data type identification unit 7 (No in step S10), the designation information writing unit 6 prompts the display unit 4 to input designation information that is a data type. Display is performed (step S12). When the input of the designation information by the user is completed (Yes in Step S13), the inputted designation information is written in a predetermined storage area of the recording medium 2 (Step S14).

  Here, when the designation information is present in step S2 (Yes in step S2), the recording medium 2 inserted into the insertion slot 3 has been recorded in the past in the data recording / reproducing apparatus 1 (or other equivalent apparatus). ) Was recorded. In step S10, the case where the data type of the recording target data is identified (Yes in step S10) is a case where the recording target data has already been reproduced in the data recording / reproducing apparatus 1. In the processing from step S10 to step S11, the data recording / reproducing apparatus 1 can store a part of recording target data for a short time by a temporary storage unit such as a buffer (not shown). During this time, the specified information writing unit 6 can generate specified information based on the data type and write it to the recording medium 2.

  In step S10, when the data type of the recording target data is not identified (No in step S10), the data recording / reproducing apparatus 1 is not reproducing the data to be recorded. In such a case, the data recording / reproducing apparatus 1 prompts the user to input designation information and writes the inputted designation information into the recording medium 2 (step S14).

(Second embodiment)
A data recording / reproducing apparatus 1A according to a second embodiment of the present invention will be described with reference to FIGS. FIG. 5 is an external view of the data recording / reproducing apparatus 1A. FIG. 6 is a block diagram of the data recording / reproducing apparatus 1A. The data recording / reproducing apparatus 1A has two insertion ports 3-1, 3-2 for inserting two recording media 2-1, 2-2. The data recording / reproducing apparatus 1A is slightly different from the data recording / reproducing apparatus 1. In the following, the same or similar parts as those in the first embodiment will be described using the same or the same reference numerals, the description thereof will be omitted or simplified, and different parts will be mainly described. In the following description, it is assumed that the recording medium 2-1 is inserted into the insertion port 3-1, and the recording medium 2-2 is inserted into the insertion port 3-2. This is for ease of understanding. . Therefore, actually, the recording medium 2-1 may be inserted into the insertion port 3-2 and the recording medium 2-2 may be inserted into the insertion port 3-1.

  As shown in FIG. 6, the data storage device 1A that records data on the recording media 2-1 and 2-2 is a data recording unit that records data on the two recording media 2-1 and 2-2. A part 9A is provided. In addition, designation information writing units which are designation information writing means for writing designation information respectively designating the types of data to be recorded in the recording media 2-1 and 2-2 in the recording media 2-1 and 2-2, respectively. 6A is provided. The data type identification unit 7 is the same as that in the first embodiment. In addition to the function described in the first embodiment, the data type confirmation unit 8A determines which type of data to be recorded for each of the recording media 2-1 and 2-2 on which the designation information is written. It has a function corresponding to a recording medium search means for searching whether it matches the designation information of the recording media 2-1 and 2-2. Further, the data recording unit 9A, for the recording media 2-1 and 2-2 searched by the data type confirmation unit 8A, stores the data whose type matches the designation information of the recording media 2-1 and 2-2. Make a record.

  Next, the operation procedure of the data type confirmation unit 8A will be described with reference to the flowchart of FIG. FIG. 7 is a flowchart showing an operation procedure of the data type confirmation unit 8A. In the flowchart of FIG. 7, the processing is started from the point where the data recording / reproducing apparatus 1A starts recording on the recording medium 1-1 or the recording medium 1-2. The data type confirmation unit 8A confirms the insertion of the recording medium 2-1 into the insertion port 3-1 (step S20). As a result of this confirmation, if the recording medium 2-1 is inserted in the insertion slot 3-1 (Yes in step S20) and the recording medium 2-1 has designation information (Yes in step S21), the data type The confirmation unit 8A reads the designation information (step S22). Note that the processing (step S28) when there is no designation information in the recording medium 2-1 (No in step S21) is as already described in FIG. After the designation information is written on the recording medium 2-1 by the designation information writing instruction in step S28, the process proceeds to the designation information reading instruction in step S22.

  Next, the data type confirmation unit 8A confirms the data type of the recording target data identified by the data type identification unit 7 (step S23). The data type confirmation unit 8A compares the designation information read in step S22 with the data type confirmed in step S23 (step S24). When the designation information of the recording medium 2-1 read in step S22 matches the data type confirmed in step S23 (Yes in step S25), the data type confirmation unit 8A sends the recording medium 2- 1 is instructed to start data recording (step S26). Even when the designation information is written to the recording medium 2-1 in step S28, the data type confirmation unit 8A instructs the data recording unit 9A to start recording data on the recording medium 2-1 (step S26). ). When recording by the data recording unit 9A is completed (Yes in step S27), the process is terminated.

  In step S25, if the designation information of the recording medium 2-1 read in step S22 does not match the data type confirmed in step S23 (No in step S25), the data type confirmation unit 8A -2 is confirmed to be inserted into the insertion port 3-2 (step S29). As a result of this confirmation, if the recording medium 2-2 is inserted into the insertion slot 3-2 (Yes in step S29) and the recording medium 2-2 has designation information (Yes in step S30), the data type The confirmation unit 8A reads the designation information (step S31). Note that the processing (step S41) in the case where there is no designation information in the recording medium 2-1 (No in step S30) is as already described in FIG.

  Next, the data type confirmation unit 8A confirms the data type of the recording target data identified by the data type identification unit 7 (step S32). If the data type of the recording target data has already been confirmed in step S23, the confirmation result is used. The data type confirmation unit 8A compares the designation information read in step S31 with the data type confirmed in step S32 (step S33). When the designation information of the recording medium 2-2 read in step S31 matches the data type confirmed in step S32 (Yes in step S34), the data type confirmation unit 8A sends the recording medium 2- 2 is instructed to start data recording (step S35). Even when the designation information is written in the recording medium 2-2 in step S41, the data type confirmation unit 8A instructs the data recording unit 9A to start recording data on the recording medium 2-2 (step S35). ). When recording by the data recording unit 9A is completed (Yes in step S27), the process is terminated.

  Even when the recording medium 2-1 is not inserted into the insertion port 3-1, and only the recording medium 2-2 is inserted into the insertion port 3-1, the above-described steps S29 to S35 to S27 are performed. Processing is performed. If neither the recording medium 2-1 nor the recording medium 2-2 is inserted into the insertion port 3-1 and the insertion port 3-2 (No in step S29), the process ends.

  Further, when the designation information of both the recording medium 2-1 and the recording medium 2-2 does not match the data type of the data to be recorded (No in step S34), or only the recording medium 2-2 is inserted. When the designation information of the recording medium 2-2 does not match the data type of the recording target data (No in step S34), the data type confirmation unit 8A replaces the recording medium 2-1 or the recording medium 2-2. A prompting display is performed on the display unit 4 (step S36). If the recording medium 2-1 or the recording medium 2-2 is exchanged as a result of this display (Yes in step S37), the process returns to step S20. If the recording medium 2-1 or the recording medium 2-2 is not exchanged in spite of this display (No in step S37), it is asked whether or not to change to designated information that matches the data to be recorded. The display is performed on the display unit 4 (step S38). At this time, after the display prompting the replacement of the recording medium 2-1 or the recording medium 2-2 is performed, the recording medium 2-1 or the recording medium 2-2 is replaced regardless of this display. A predetermined determination time is required until it is determined that there is not. This determination time is, for example, about 5 seconds. Alternatively, a display for prompting the replacement of the recording medium 2-1 or the recording medium 2-2 and a display for asking whether or not to change to designated information that matches the recording target data are simultaneously performed on the display unit 4, and the user can either May be selected.

  In step S38, as a result of performing a display on the display unit 4 asking whether or not to change to designated information that matches the recording target data, if there is a user change instruction from the operation unit 5 (Yes in step S39), the recording is performed. The specification information is changed to match the target data (step S40). Accordingly, the process returns to step S20. If the user does not replace the recording medium 2-1 or 2-2 and does not change the designation information, a flow loop is formed between step S 37 and step S 39 in this flowchart. Therefore, in such a case, the processing may be stopped after a predetermined time has elapsed.

  Next, another operation procedure of the data type confirmation unit 8A will be described with reference to the flowchart of FIG. FIG. 8 is a flowchart showing an operation procedure of the data type confirmation unit 8A. The difference from the flowchart of FIG. 7 is that the process of recording the same data on the recording medium 2-1 and the recording medium 2-2 is included in the flowchart of FIG. Steps S50-1, S50-2, Steps S51-1, S51-2, Steps S52-1, S52-2, Steps S55-1, S55-2 are parallel processes, but the explanation is simplified. Therefore, the explanation will be made without dividing.

  As shown in FIG. 8, when the data type confirmation unit 8A confirms the insertion of the recording media 2-1 and 2-2 into the insertion ports 3-1 and 3-2 (steps S50-1 and S50-2), The presence / absence of designation information written in the recording media 2-1 and 2-2 is determined (steps S51-1, S51-2). When the designation information is written in the recording media 2-1 and 2-2 (Yes in steps S51-1, S51-2), the data type confirmation unit 8A reads the designation information (step S52-1, S52-2). In addition, when the designation information is not written in the recording media 2-1 and 2-2 (No in Steps S51-1 and S51-2), the data type confirmation unit 8A writes in the designation information writing unit 6A. The process is instructed (steps S65-1, S65-2). This writing process is as already described with reference to the flowchart shown in FIG. After the designation information is written to the recording medium 2-1 and the recording medium 2-2 by the designation information writing instruction in steps S65-1 and S65-2, the recording medium 2-1 and the recording medium in steps S56 and S60 are recorded. Processing shifts to a data recording start instruction for 2-2.

  Next, the data type confirmation unit 8A confirms the data type of the recording target data identified by the data type identification unit 7 (step S53). The data type confirmation unit 8A compares the designation information read in step S53 with the data type confirmed in steps S52-1 and S52-2 (step S54). When the designation information of the recording medium 2-1 read in step S52-1 matches the data type confirmed in step S54 (Yes in step S55), the data type confirmation unit 8A sends a recording medium to the data recording unit 9A. A data recording start instruction is given to 2-1 (step S56). Further, when the designation information of the recording medium 2-2 read in step S52-2 matches the data type confirmed in step S54 (Yes in step S57), the data type confirmation unit 8A A data recording start instruction is given to the recording medium 2-2 (step S58). As a result, the same data is recorded on both the recording media 2-1 and 2-2.
