BACKGROUND OF THE INVENTION
The present invention relates to a recording / reproducing apparatus and a recording / reproducing processing program for ripping and reproducing from a music recording medium such as a music CD to an HDD.
[0002]
[Prior art]
2. Description of the Related Art A recording / reproducing apparatus that takes in (ripped) music data from a music recording medium such as a music CD (CD-DA: Compact Disc Digital Audio), stores the data in a hard disk device (HDD), and the like is known.
A user of such a recording / reproducing apparatus normally keeps the original music CD itself and uses the music data ripped on the HDD for actual listening. Then, the captured album is played back as it is, or is played back using a playlist that stores the playback order of favorite songs.
In such a recording / playback device, if a song recorded on the HDD is deleted, even if you later want to restore it to the state before the deletion, you may not remember which song was deleted, There is a problem that the song is not registered in the playlist.
[0003]
In general, various techniques have been proposed for restoring data that has been recorded on a recording medium to a state before the deletion when the data is deleted.
One method is to delete only management information without deleting the entity when deleting data (see, for example, Patent Document 1). However, this method may not be able to reliably recover.
In addition, it has been proposed to leave a deletion file on the HDD (see, for example, Patent Document 2). However, this method has a problem of squeezing the capacity of the HDD.
Further, in the recording / playback apparatus for recording music data and video data, the music information is obtained from a server on the Internet when the music information recorded on the HDD is broken in the case of acquiring the music via the Internet. The thing to recover is proposed (refer patent document 3). However, this method requires authentication from the server, and the configuration is complicated.

[0010]
FIG. 3 is a flowchart showing a processing flow when new music data is taken in from a music CD.
As described above, when the music CD 11 is inserted into the CD-R / RW device 6 and the import is instructed, ripping for each album is started.
First, a disc ID (Disc ID) for specifying the music CD is generated from a TOC (table of contents) written in the lead-in area of the music CD (step S1). Here, the disc ID is generated by an algorithm specified by the music information database to be used. For example, the disc ID is generated from the number of tracks of the music CD included in the TOC and the total performance time. . At this time, the generated disk ID and the TOC information of the music CD are separately stored.
Then, the music information database published on the Internet is accessed, and the music information such as artist name, album name, song name list, etc. of the music CD is obtained using the disk ID generated in step S2 as a key, and the disk Saved together with the ID (step S3). If information corresponding to the CD is not obtained from the music information database, the user can input the artist name, album name, song name list, etc. of the music CD using the input unit 3.
In parallel with these processes, music data included in the CD is ripped for each track to create music data (step S3). This process may be executed after step S1 or S2.
In this way, information such as the artist name, album name, song name list, etc. of the ripped music CD is acquired (step S2), and the song data of each song is imported (step S3), and then the process proceeds to step S4. A song ID for identifying each song is generated, song information management data is created, and the entity of the song data is stored.
Hereinafter, the process of step S4 will be described.
[0011]
First, how the ripped music data is managed in the HDD 5 will be described with reference to FIG.
In the present invention, for song data recorded in the HDD 5, an artist name table 21 in which artist names are recorded, album name tables 22, 23,... In which album names are recorded for each artist, and each album. A song name table 24, 25,... In which the song names contained therein are recorded is created, and each item in the artist name table 21 stores an artist name and a pointer to the artist's album name table 22, 23,. Each item in the album name table stores a pointer to the song name table 24, 25,... For recording the album name and the song names included in the album in the order of the track number. Stores the name of the song and a pointer to the song data entity of the ripped song It has to.
For each song, the item number of the artist name in the artist name table 21, the item number in the album name table 22, 23,... Of the album containing the song, and the song name table 24 of the album , 25,... Is the song ID (Song ID) of the song. For example, in the song ID “135” shown in FIG. 4, the artist name of the song is the first item (A) in the artist name table, and the album name containing the song is the album name of artist A. The third item (AC) in the table indicates that the song is the fifth song (song name acc) of the album AC.
Accordingly, by following the links of the artist name table 21, the album name tables 22, 23,... And the song name tables 24, 25,. It is possible to reach the substance of the song data of the song from the pointer recorded in the song item.
[0012]
As described above, when the music CD 11 is inserted into the CD-R / RW device 6 and ripping is started, the artist name, album name, song name list, etc. of the music CD are acquired from the song information database in the step S3. .
In step S4, first, based on the acquired artist name data, the artist name table 21 is referred to and it is determined whether or not an item corresponding to the artist of the music CD exists in the artist name table 21. To do. If it does not exist, an item for the artist is created in the artist name table 21, a link for the artist's album name table is created to create the album name table, and the obtained album name data is stored. In addition, a link for the song name table of the album is created to create the song name table, and the song names are written in order of track numbers based on the acquired song name list. When ripping for the first time, the artist name table 21 is created and the above processing is performed.
On the other hand, when the name of the artist is described in the artist name table 21, it is determined whether or not there is an album name item acquired from the music information database with reference to the artist's album name table, If not, add an item for the album name, create a link for the song name table, create the song name table, and write the song names in track number order in the song name table based on the acquired song name list To do.
In this way, for each song included in the ripped music CD, the item number of the artist in the artist name table 21 and the item number of the album to which the artist belongs in the album name table 22 (23,...). , And the item number (that is, the track number) in the song name table 24 (25,.
Then, the substance of each piece of music data ripped in step S3 is stored in the HDD 5, and data specifying the storage location is described in the item of the music in the song name tables 24, 25,.
In this way, the substance of ripped music data can be saved.
[0013]
As described above, in the present invention, a hierarchically configured table relating to the category to which the song belongs, such as an artist name table, an artist album name table, and a song name table included in the album, is created. The song ID of the song is obtained by combining information indicating the item to which the song belongs. As a result, it is possible to access the substance of the song data of the song by sequentially tracing each table based on the song ID.
Note that the hierarchically configured table related to the category to which the song belongs is not limited to the above three types, and other tables such as a table of the music genre to which the song belongs can be used. Further, the number of types of tables is not limited to the above-described three types, and the artist name table can be omitted and only the album name table and the song name table can be provided.
[0014]
Next, the music information management data will be described with reference to FIG.

In the location of the playlist information in, information indicating the number (ID) of the playlist including the song and the order of the song in the playlist is stored. At the stage of ripping music data from the music CD, nothing is written in this playlist information column, but it is included in the playlist when the playlist is created or edited by the user. In this column of the song information management data 13 of the song, a number for identifying the playlist and a number indicating the reproduction order of the song in the playlist are written.
Each playlist stores the song IDs of the songs included in the playlist (that is, information corresponding to the address of the song data entity) in the order of performance.
[0015]
FIG. 5B is a diagram for explaining information that can be obtained from the song information management data 13.
As shown in this figure, the song ID included in the song information management data 13 indicates which song of which album of which artist the song is, and the song is included from the disc ID and the track ID. The information for identifying the music CD that has been recorded and the track number in the CD are known. In addition, from the playlist information, the information of the playlist including the song is known. In the example shown in the figure, since “53” is described in the playlist information, it can be seen that this song is registered in the third of the fifth playlist. When this song is registered in a plurality of playlists, the plurality of pieces of information are described in the playlist information column.
[0016]
As described above, after the song information management data 13 is created for each song, the HDD data management file (FIG. 2) that combines the song information management data 13 corresponding to all the songs recorded in the HDD device 5 into one. 14) is created and stored (step S5).
