The operation of each unit is controlled according to the control program.

  The CD drive unit 12 includes a CD storage unit 12-1, a CD playback unit 12-2, and the like. The CD storage unit 12-1 stores a CD from which data is read by the CD playback unit 12-2. The CD playback unit 12-2 searches for a target address on the disc stored in the CD storage unit 12-1 and loaded in the CD playback unit 12-2 and corresponds to the searched address. The music data is optically read by an optical pickup to reproduce the music data.

  An optical pickup (not shown) moves in the radial direction of the disk by a thread controlled by a tracking thread servo circuit (not shown) during disk reproduction, and is rotated by a spindle motor controlled by a spindle servo circuit (not shown). By irradiating the driven disk with laser light, data recorded on the disk is extracted (ripped) from the intensity of the reflected light.

  Specifically, the reflected light is converted into an electrical signal, and the electrical signal is processed to obtain a music data signal and TOC (Table Of Contents) information. The music data acquired from the CD is recorded in the music data storage area in the RAM in the control means 11, and the TOC information acquired from the CD is recorded in the TOC information storage area in the RAM in the control means 11.

  FIG. 2 is a diagram for explaining the configuration of the TOC information.

  The TOC information is recorded in the lead-in area of the CD. As shown in FIG. 2, the TOC information includes the number of tracks recorded on the CD for each CD, the start address of each track on the CD, and each Information such as track playing time is associated. For example, for track 1, the track start address is “0x1” and the performance time is “aa: aa”.

  The recording control unit 13 is for controlling recording of the music data read from the CD or the like and temporarily stored in the music data storage area in the RAM of the control unit 11 to the HDD unit 14. The music data read from the music CD is recorded as a file in the HDD unit 14, but the recording control unit 13 records the music data recorded in the music CD in the HDD unit 14 in a different recording mode depending on the contents.

  That is, in the case of music data having a silent time between songs of music data recorded for each track, such as a general music CD, the recording control unit 13 starts from this music CD. The read music data consisting of one track is recorded as one file in the HDD unit 14 (this is referred to as a first recording form).

  On the other hand, when the music data recorded for each track on the music CD is music data that does not have a silent time between songs, that is, music data recorded so-called live recording (recorded by connecting songs). The recording control unit 13 records live-recorded music data composed of a plurality of tracks read from the music CD as one file in the HDD unit 14 (this is referred to as a second recording mode).

  Here, the recording control unit 13 uses the online database service for music CD information provided by CDDB (CD DataBase), and acquires CD information related to the CD via the Internet based on the TOC information read from the CD. The music data recorded for each track on the music CD is music data having a silent time between songs based on the information on the recording form of the music data included as additional information in the CD information. It is determined whether the music data is present or not.

  Note that the CD information that can be acquired from the CDDB includes the album name (CD title name), artist name, music genre, track number and song name of each song, and additional information related to the song. ing.

  In addition, when the TOC information read from the CD includes information related to the recording format of the music data recorded on the CD, the recording control unit 13 does not access the CDDB and does not access the CDDB. It can be determined whether the music data recorded for each track on the CD is music data having a silent time between songs or not.

  The data recording / reproducing apparatus 10 records (records) the music data of all tracks recorded on the CD designated by the user or the music data of the track number designated by the user in one file on the HDD unit 14. When recording music data of a CD on the HDD unit 14 with this function, the user can set the “live recording” mode from the input unit 18.

  When the “live recording” mode is set by the user operation from the input unit 18 in the recording instruction from the user, the recording control unit 13 stores the music data of all tracks recorded on the CD designated by the user, Alternatively, the music data of the track number designated by the user is recorded in the HDD unit 14 as one file.

  Furthermore, the recording control unit 13 includes a compression encoder unit for compressing and encoding music data to be recorded on the HDD unit 14 in accordance with instructions from the control unit 11. Therefore, music data read from a CD or the like and temporarily stored in the music data storage area in the RAM in the control means 11 is stored in the HDD using dedicated software stored in the ROM in the control means 11. (Read). That is, the music data of the CD is converted into a WAV file which is a standard audio file, and is written to the HDD as it is under the control of the recording control unit 13, or the WAV file is converted to MP3 (MPEG-) via an encoder (compression unit). According to an arbitrary compression format such as 1 / AUDIO Layer 3), the data is encoded (compressed) at an arbitrary bit rate (compression rate) and written to the HDD. When music data is compressed and written to the HDD, decoding software for decoding (expanding) the music data is also recorded on the HDD.

  The HDD unit 14 is a large-capacity recording medium that is built in the data recording / reproducing apparatus 10 and stores music data such as music read from a CD or the like as a file. Here, when music data read from a general music CD in which music data is recorded for each track is recorded in the HDD unit 14 as a file, the music data of each track is respectively recorded according to the first recording mode. It is configured to be recorded on the HDD unit 14 as one file, or music data consisting of a plurality of tracks is recorded on the HDD unit 14 as one file according to the second recording format.

  FIG. 3 is a diagram for explaining the configuration of each file recorded in the HDD unit 14.

  FIG. 3A shows a first recording in which music data consisting of one track is recorded as one file when music data read from a music CD in which music data is recorded for each track is recorded in the HDD unit 14. A file created when data is recorded according to the form is shown. Specifically, a header portion of each file created when music data of a music CD having TOC information as shown in FIG. 2 is recorded in the HDD portion 14 in the first recording form is shown.

  As shown in FIG. 3A, as the header portion of the file of the HDD unit 14, for each file, the address information of the music data on the HDD unit 14, the title name of the music CD, and the corresponding track on the CD An example is shown in which numbers, file title names (song names), and performance times are recorded in association with each other. For example, for file 1, “00aa” is the address information of the music data on the HDD unit 14, “title X” is the CD title name, “1” is the track number on the CD, and “song A is the song name. "Aa: aa" is recorded as the performance time.

  Among these pieces of information, performance time information corresponding to the track number is included in the TOC information acquired from the CD, and song title information corresponding to the CD title name and file number is included in the CD information that can be acquired from the CDDB. ing.

  FIG. 3B shows a second example of recording music data consisting of a plurality of tracks as one file when recording music data read from a music CD in which music data is recorded for each track in the HDD unit 14. A file created when data is recorded in a recording form (live recording form) is shown.

Yes.

  As shown in FIG. 3B, for each file corresponding to a track of music data that is not a live recording as a header portion of the file of the HDD unit 14, the file on the HDD unit 14 is the same as in FIG. The music data address information, the title name of the music CD, the track number on the corresponding CD, the file title name (song name), and the performance time are recorded in association with each other.

  In addition, the file corresponding to the music data track of live recording is recorded in association with only the address information of the music data on the HDD unit 14 and the title name of the music CD. For example, for file 2, “00bb” is recorded as address information of music data on the HDD unit 14, and “title X” is recorded as the CD title name.

  Among these pieces of information, performance time information corresponding to the track number is included in the TOC information acquired from the CD, and song title information corresponding to the CD title name and file number is included in the CD information that can be acquired from the CDDB. ing.

  When the music data composed of a plurality of tracks among the music data recorded on the HDD unit 14 is recorded on the HDD unit 14 as one file, the file creation unit 15 tracks the plurality of music data included in the one file. This is for creating an album management file to be managed in units based on the TOC information acquired from the CD and the CD information that can be acquired from the CDDB as needed by this TOC information.

  When the data storage / reproduction device 10 reproduces the music data recorded in the HDD unit 14 and outputs the music data from the speaker unit 19, the data storage / reproduction device 10 reads the music data from the HDD unit 14 based on the file number with reference to the file. In the file shown in 3 (b), for example, for music data managed as file number 2, each user desires in the same file regardless of the live recording data actually composed of a plurality of tracks. Track up (FF) or track down (RW) processing cannot be performed.

  Further, when the music storage / playback apparatus 10 displays the title and performance time of the music data being played back on the display unit 17 when the music data is played back, the data storage / playback apparatus 10 refers to the file and refers to the song name or In order to read out the performance time, in the file shown in FIG. 3B, for example, music data managed as file number 2 is actually stored in the same file despite the live recording data consisting of a plurality of tracks. The song name and performance time of each currently playing track cannot be displayed.

  Therefore, when the music data composed of a plurality of tracks is recorded on the HDD unit 14 as one file, the file creation unit 15 identifies and manages the music data corresponding to each of the plurality of tracks included in the one file. An album management file (management information) is created, and the created album management file is stored in the RAM in the control means 11.

  FIG. 4 is a diagram for explaining the configuration of the album management file.

  FIG. 4 shows an example of an album management file for identifying and managing music data corresponding to each of a plurality of tracks included in one file. As shown in FIG. 4, as an album management file of the HDD unit 14, for each track included in one file, a title name (song name) corresponding to the track number and a start time are stored in association with each other. Yes. For example, for track number 2 managed as file number 2, “song B” is stored as the song name, and “b′b ′: b′b ′” is stored as the start time. Similarly, for the track number 3, “Song C” is stored, and “c′c ′: c′c ′” is stored as its start time.

  Among these pieces of information, start time information corresponding to the track number is calculated from each track performance time included in the TOC information acquired from the CD, and song name information corresponding to the track number is CD information that can be acquired from the CDDB.

Write. At this time, music data composed of a plurality of tracks recorded live, music data of all tracks recorded on the CD designated by the user together with the “live recording” mode setting, and music of the track number designated by the user Data is written as one file.

  In step S507, an album management file is created for music data composed of a plurality of tracks written in the HDD unit 14 as one file, and the created album management file is stored in the RAM in the control means 11.

  On the other hand, in step S508, the music data recorded on the designated track desired to be recorded is read from the CD mounted on the CD playback unit 12-2 to the RAM in the control means 11. In step S509, it is determined whether reading of all music data of the designated track desired to be recorded has been completed. If reading has been completed, the process proceeds to step S510. If reading has not been completed, step S509 is performed. The process of S509 is repeated.

  In step S510, the music data read into the RAM is subjected to compression processing according to the MP3 compression format by the encoder (compression unit) of the recording control unit 13 as necessary. In step S511, the compressed music data is transferred to the HDD unit 14. The writing process is terminated. At this time, music data consisting of one track is written as one file.

  In the above-described embodiment, it is determined whether or not to proceed to the recording process according to the second recording form in step S503. The determination process as to whether the music data is live recorded in step S501 and the “live recording” in step S502. However, the present invention is not limited to this, and may be performed based on only one of the determination processes.

  In the above embodiment, the case where MP3 is used as the compression format has been described. However, the present invention is not limited to MP3, and other compression methods such as AAC (MPEG-2 / Advanced Audio Coding) can be applied. It is.

  As described above, according to the data recording / reproducing apparatus of the present invention, the data consisting of one track read from the first recording medium (CD) in which the data is recorded for each track by the user operation or the like is stored as the first file. A first recording form recorded on the second recording medium (HDD) and data consisting of a plurality of designated tracks read from the first recording medium (CD) are recorded as one file on the second recording medium. The second recording form to be selected can be selected.
