[0064]
The disc recording / reproducing apparatus 2 writes a disc management number, which is an identification number for managing the disc, in the lead-in area of the recording disc DR1 (Step S8).
[0065]
On the other hand, if the control unit 12 determines that the recording disk DR1 is assigned a disk management number (YES in step S7), it skips step S8 and proceeds to step S9.
[0066]
The control unit 12 instructs the disk recording / reproducing apparatus 2 to record the music order number (track number), and the disk recording / reproducing apparatus 2 stores the music order number (track number) in the lead-in area of the recording disk DR1. ) Is written (step S9).
[0067]
Here, first, the control unit 12 specifies the music order number (track number) to be written from the notification received from the disk reproducing device 1 and the disk recording / reproducing device 2 in step S1. That is, the control unit 12 writes the track to which the music data is to be written from the music sequence number (track number) recorded in the lead-in area of the reproduction disk DP1 and the music sequence number recorded in the lead-in area of the recording disk DR1. Identify the number.
[0068]
For example, if the number of music pieces recorded on the reproduction disk DP1 is 12 and the number of music pieces recorded on the recording disk DR1 is 5, the control unit 12 sets the track numbers for writing music data to 6 to 17 is specified.
[0069]
Then, the control unit 12 sends the specified music order number (track number) to the signal processing unit 16, and the signal processing unit 16 notifies the disc recording / reproducing device 2.
The disc recording / reproducing apparatus 2 writes the data in the lead-in area of the recording disc DR1 according to the notification received from the signal processing unit 16.
[0070]
Thereafter, the control unit 12 instructs the disk recording / reproducing device 2 via the signal processing unit 16 to write character data to the recording disk DR1. That is, the control unit 12 extracts character data to be written to the recording disk DR1 from the edit data storage area 22 of the RAM 11, and sends the character data to the disk recording / reproducing apparatus 2 via the signal processing unit 16.
[0071]
The disc recording / reproducing apparatus 2 writes the received character data into the lead-in area of the recording disc DR1 (Step S10).
[0072]
Next, the control unit 12 sends an instruction to the disk reproducing device 1 to start reproducing the music data.
[0073]

Store. Also, the disc reproducing apparatus 1 sends data corresponding to the first few seconds of each track of the reproduced music data to the RAM 11 via the signal processing unit 16 and stores the data in the management data storage area 21 as an intro portion of each music. Store.
Thereby, the disk information processing device 4 can register information on the recording disk DR1 on which new music data has been recorded, and can manage the user edited disk in an integrated manner.
[0076]
Further, when the disk recording / reproducing device 2 writes music data, the control unit 12 provides a control area at the head of an area where music data of each music is recorded on the recording disk DR. Is recorded as a music order number (track number).
[0077]
When the control unit 12 finishes writing the music data to the recording disk DR1 in step S11, the control unit 12 ends the disk reproduction / recording process.
[0078]
In this way, the character data is written on the recording disc DR1 together with the music data, and can be read out as an index title during reproduction.
[0079]
For example, when the recording disk DR1 on which the music data is recorded by the above processing is set in the disk reproducing device 1, the disk reproducing device 1 reads the character data from the lead-in area of the recording disk DR1 and sends the read character data to the sound / image output device 3. The contents displayed on the screen can be presented to the user in an easy-to-understand manner.
[0080]
Also, a disc management number is assigned to the recording disc DR1, and the recorded contents (disc management number, song order number, character data, etc.) are stored in the management data storage area 21, so that the disc information processing device 4 Can be managed comprehensively.
[0081]
For example, when the recording disk DR1 is not set in any of the disk reproducing device 1 and the disk recording / reproducing device 2, and the user instructs the display of the management data from the input unit 15, the control unit 12 The data stored in the data storage area 21 can be output to the sound / image output device 3 via the signal processing unit 16. That is, the control unit 12 displays the disc management number, the song order number (track number), and the character data stored in the management data storage area 21 on the screen of the sound / image output device 3, and outputs the intro portion of each song as sound. Can be done.
Thereby, the user can easily confirm the recorded contents of the self-made recording disc DR1.
[0082]
(Character data selection processing)
Next, the character data selection processing executed by the control unit 12 in step S4 of the disk reproduction / recording processing will be described with reference to the flowchart shown in FIG.
[0083]
After starting the character data selection process, control unit 12 waits for input unit 15 to receive a key input from the user (NO in step S20).
[0084]
The control unit 12 detects that the input unit 15 has received a key input (YES in step S20), searches the character data storage area 20 according to the key input received by the input unit 15, and stores it in the recording disc DR1. Specify the character data to be written.
Hereinafter, a process for the control unit 12 to specify character data will be described using a specific example.
[0085]
For example, when the user sets a character “Matsuda” by operating a direction key (not shown) provided in the input unit 15, the control unit 12 causes the character data (entry word) stored in the character data storage area 20 to be stored. Among them, an artist name that includes the character "Matsuda" is searched (step S21).
[0086]
The control unit 12 sends the search result to the signal processing unit 16, and the signal processing unit 16 converts the search result into an image signal and causes the sound / image output device 3 to display the image on the screen (step S22).
[0087]
FIG. 8 shows an example of the display screen at this time.
As shown in the figure, in this example, the sound / image output device 3 displays an artist name including the characters "Matsuda" on the screen together with the cursor CS.
Thereafter, the user instructs the movement of the cursor CS from the input unit 15 and inputs the item “Matsuda
Is selected, the control unit 12 confirms with the user whether or not to update the character data stored in the character data storage area 20 to the latest one by displaying the screen on the sound / image output device 3. (Step S23).
[0088]
When determining that the character data is to be updated (YES in step S23), control unit 12 executes a latest data acquisition process of acquiring the latest character data by communication I / F 10 (step S24).
The latest data acquisition processing will be described later.
[0089]
On the other hand, if the control unit 12 determines that the character data is not updated, the control unit 12 skips the latest data acquisition process in step S24 and proceeds to step S25.
[0090]
The control unit 12 extracts the character data indicating the title of the song associated with the item “Seiji Matsuda. (Step S25).

[0123]
At this time, the edit data storage area 22 stores the disk management numbers of the reproduction disks DP10 to DP12 in which the music to be written on the recording disk DR2 is recorded and the track numbers in which the music is recorded in the music order of the recording disk DR2. It is recorded in association with the number (track number).
Thereby, the control unit 12 can specify the order in which the disk reproducing device 1 reproduces the music data from the reproducing disks DP10 to DP12.
[0124]
When the user adds character data to an unnamed song (indicated by the screen display “No Name” in FIG. 14), the control unit 12 performs a process similar to the character data selection process. By executing, character data to be recorded can be selected.
[0125]
Thereafter, in step S44 of FIG. 13, control unit 12 waits for the user to press the recording button of input unit 15 again to instruct recording start (NO in step S44).
[0126]
When receiving the instruction to start recording (YES in step S44), control unit 12 determines whether or not a disc management number has been assigned to recording disc DR2 based on the data received from disc recording / reproducing apparatus 2 in step S40. Is determined (step S45).
[0127]
If the control unit 12 determines that the disc management number is not assigned to the recording disc DR2 (NO in step S45), it instructs the disc recording / reproducing apparatus 2 to write the disc management number.
[0128]
The disc recording / reproducing apparatus 2 writes a disc management number, which is an identification number for managing the disc, in the lead-in area of the recording disc DR2 (Step S46).
[0129]
On the other hand, when determining that the recording disk DR2 has a disk management number (YES in step S45), control unit 12 skips step S46 and proceeds to step S47.
[0130]
The control unit 12 instructs the disk recording / reproducing apparatus 2 to record the music order number (track number), and the disk recording / reproducing apparatus 2 stores the music order number (track number) ) Is written (step S47).
[0131]
The control unit 12 reads the character data from the edit data storage area 22 and sends it to the disk recording / reproducing device 2 via the signal processing unit 16.
The disk recording / reproducing device 2 writes the received character data into the lead-in area of the recording disk DR2 (Step S48).
[0132]
Next, the control unit 12 notifies the disc reproducing apparatus 1 of the order of the discs and tracks to be reproduced according to the disc management numbers and the track numbers of the recording discs DP10 to DP12 in the data held in the edited data storage area 22. . That is, when the disc reproducing apparatus 1 finishes reproducing a certain music, the control unit 12 sets the disc management number and the track number of the reproduction disks DP10 to DP12 in which the music to be reproduced next is recorded from the editing data storage area 22. It reads and notifies the disk playback device 1.
[0133]
In accordance with the notification received from the control unit 12, the disk reproducing device 1 reproduces the music data while replacing the reproducing disks DP10 to DP12, and sends the data to the disk recording / reproducing device 2.
The disk recording / reproducing device 2 sequentially records the music data received from the disk reproducing device 1 on the recording disk DR2 (Step S49).
[0134]
The control unit 12 detects that the reproduction / recording of the music data has ended, and ends the music selection recording process.
[0135]
In this manner, the disk reproducing device 1 sequentially reproduces the reproducing disks DP10 to DP12, and the disk recording / reproducing device 2 records the data on the recording disk DR2, thereby selecting a song from a plurality of reproducing disks. Music data and character data can be easily recorded.
[0136]
As described above, in the disk recording / reproducing system, the character data recorded on the disk by the disk information processing device 4 is comprehensively managed together with the disk management number and the like, and is stored in the RAM 11. In the disk information processing device 4, the communication I / F 10 acquires character data from an external data storage organization and stores the character data in the character data storage area 20. Thus, the user can select and input character data to be written to the recording disc by a simple operation according to the screen display.
In particular, when inputting character data to a disk-shaped recording medium such as a high-density recording medium such as a DVD that can store a large number of music pieces, the input of the character data by selecting characters one by one is more difficult than inputting character data. The labor can be greatly reduced.
[0137]
The disc recording / reproducing system stores data for managing the recording disc DR on which the disc recording / reproducing apparatus 2 has written, in a management data storage area 21 in the RAM 11 of the disc information processing apparatus 4. be able to. Then, the control unit 12 can cause the audio / image output device 3 to output the data stored in the management data storage area 21 as a sound and a screen. Thereby, the user can easily confirm the recorded content of the recording disc DR edited by himself.
