By the way, there is no problem when the title information is recorded in the second UTOC when all the audio data blocks (songs) have already been recorded on the disk. However, when a plurality of songs are recorded on a disc, the title information of the song to be recorded is set to MD
It is impossible to input the information to the system, and the user has to wait for the start or end of recording of the song to input the title information, which is time-bound for the user. For example, when ten songs of a CD are recorded on an MD, the title information of the first song can be input to the MD after the recording of the first song is started. It was impossible to input the title information of the song. Therefore, generally, the title information of all the songs is input after the recording of all the songs is completed, and the total of the recording time of the songs and the input time of the title information becomes relatively long.

An object of the present invention is to provide an information recording / reproducing apparatus and method capable of rationally recording a title on an MD or a similar recording medium.

Embodiments and Examples Next, embodiments and examples of the present invention will be described with reference to the drawings.

An information recording / reproducing apparatus according to an embodiment of the present invention digitally records and reproduces audio information using an MD (mini-disc) 1 as a well-known magneto-optical recording medium shown in principle in FIG. It is a disk recording / reproducing device, that is, an MD recorder. The MD 1 has a spiral track 2 in which a track format for recording and reproducing data by a CLV (constant linear velocity) method is recorded. FIG. 1 (B)
1 shows the outline of the format of the track 2 in FIG. The track 2 is roughly divided into a rewritable TOC (index or table of contents table) area 2a, a rewritable UTOC (user index or table of contents table) area 2b as a table of contents information area, and a rewritable user as a main data area. And a data area 2c. In FIG. 1B, the user data area 2c includes, for example, first and second data in the user data area 2c.
And third audio data blocks (songs) D1, D2, D3
Is recorded, and it is possible to record another audio data block (song) after the recording area of the third data block (song) D3. The first, second and third audio data blocks D1, D2 and D3 are usually the first, second and third music pieces.

In the MD1, the recording areas of the first, second and third music pieces, that is, the audio data blocks D1, D2 and D3 are managed in units of first, second and third tracks. Then, title information can be written in each track (song). One track (one music area) of MD1 is composed of a combination of one or more parts (sections). It should be noted that a part means a continuous recording area of audio data. In FIG. 1, the first, second and third audio data blocks (songs) D1, D2 and D3 are regularly arranged in the first, second and third parts P1, P2 and P3, but one audio data block Data blocks (songs) can be distributed and arranged in a plurality of parts. For example, the first audio data block (song) D1 can be distributed and arranged in the first and third parts P1, P3. Parts in the user data area 2c are managed in the UTOC area 2b. Since the UTOC area 2b has a management capability of 255 parts, the user data area 2c can be divided into 255 parts at the maximum. The user data area 2c
The length of one part can be arbitrarily determined by the user.

The UTOC area 2b for managing the user data area 2c in FIG. 1 has five sectors 0 to 4 as described above. UTOC-0 among them
2 and 3 show the outline of the format of the first and second UTOC areas indicated by UTOC-1 and UTOC-1. The first UTOC region 3 shown in FIG.
OC-0 has roughly nine regions 3a to 3i.
In the header section area 3a, whether this is TOC or UTOC
Various kinds of information including flag information indicating whether or not are stored. The First TNO area 3b indicates the first music number. If this is 0 or nothing is recorded, it is a disc on which no music is recorded, and if it is 1, it indicates that at least one music is recorded. Last
The TNO area 3c indicates the last music number. If this is 0 or nothing is recorded, it is a disc on which no music is recorded, and if it is 1 or more, it indicates that the number of music is recorded. The information in the Last TNO area 3c is used when recording title information according to the present invention. The buffer area 3d is filled with NULL (0). The P-EMPTY area 3e indicates the head pointer (head slot number) of an empty slot. In the MD, a slot for storing the address of a part is provided for managing the part existing on the user data area 2c in FIG. There are 255 slots in the slot area 3i, which will be described later, having an area of 8 bytes. Of these, a slot which does not indicate any part existing in the user data area 2c is managed in the P-EMPTY area 3e. An empty slot managed in the P-EMPTY area 3e is treated as not indicating any address in the user data area. The P-FRA area 3f indicates a head pointer (head slot number) of a slot that points to a reusable free part. That is, the leading part data number indicating a free part having six or more clusters is stored here. P-TNO (1) to P-TNO (255)
255 track (song) data area 3 indicated by
In g, the pointer of the top slot of each track, that is, each song, that is, the top slot number is stored. When a plurality of music pieces of MD1 are continuously reproduced, P-TNO (1)
Reproduction proceeds in the order of .about.P-TNO (255). Therefore, P-TNO (1) to P-TNO (255) are the table of contents of the music, and the reproduction order of a plurality of music can be changed by changing the slot number recorded here. The buffer area 3h is NULL like the buffer area 3d.
Filled with (0). The slot area 3i includes first to 255th slots (divided areas) for managing parts.
PD1 to PD255. Slot PD1 to PD255
Consists of 8 bytes each. In each of the first to 255th slots PD1 to PD255, a start address, an end address, and a Link-P (link pointer) of the parts making up the music are written. It should be noted that the user data area 2c shown in FIG. 1 is not always divided into 255 parts, and is generally divided into parts significantly less than 255 parts. User data area 2 for all of PD1 to PD255
The address to c is not written. Link-
P is called a “link pointer”, and is used when one music piece is divided and recorded into a plurality of parts. If the music piece has the next part, the slot number of the slot indicating the address of the next part (Pointer) is written, and if there is no subsequent part, 0 is written. The slot number means a value indicating the order of the first to 255th slots PD1 to PD255. The slot in the slot area 3i is a P-EMPTY area 3
e, P-FRA region 3f, P-TNO (1) to P-TN
It is always linked to any one of the track data areas 3g indicated by O (255). That is, the slot corresponding to the rewritable part (where the address of the rewritable part is recorded) is P-FRA, and the empty slot is P-E.
It is linked to MPTY. In the case of a so-called raw disc where no music is recorded, only the first slot is P
-In FRA, all other slots are P-EMPTY
, And both the start address and the end address in all slots are 0. When a new song (audio data block) is recorded on the MD1, a new part is created on the user data area 2c. Then, the start address and the end addr of this new part are represented by P-
Writing is performed to one of the slots linked to the EMPTY, the slot is removed from the link of the P-EMPTY, and the slot is linked to the track data area 3g. Thus, a new slot corresponding to the new part is written in the slot area 3i. In addition, the track data area P-TNO (n) for the last track (final tune) up to now in the track data area 3g (where n is an arbitrary integer) is a track data area one step behind. P-TNO (n + 1) contains the start slot number P of the new song
D is written.

Now, as an example, the reproduction procedure of the first tune will be described. The slot number indicating the head slot of the first tune of the P-TNO (1) of the track data area 3g in the first UTOC area 3 of FIG. Is read. This allows
Since the start slot number of the first music piece is known, the slot of the slot area 3i corresponding to this slot number is read. When the head slot number of the first music piece indicates the first slot, the head address, end address, and Link-P of the first slot PD1 are read. This makes it possible to read actual data from the start address to the end address of the first part P1 in which the first music piece of the user data area 2c in FIG. 1 is recorded. If the first tune is recorded only in the first part P1, the Link- of the first slot PD1 in FIG.
Since 0 is recorded in P, the reading of the first music ends when one part is read. Also, if the first
If the program is recorded in both the first and second parts P1 and P2 in FIG. 1, the first slot PD1 in FIG.
The Link-P is read to read the start address and the end address of the second slot PD2 and the Link-P, and based on this, the actual data of the second part P2 in FIG. 1 is reproduced. The reproduction of the second and subsequent songs is performed in the same manner as the first song.

(2), P-TNO (3) is read out and P-
TNA (1), P-TNA (2), and P-TNA (3) are read out, and the titles of the respective songs are written in TS1 to TS
9 and can be displayed on the display 17.
That is, the title of the song can be displayed on the display 17 in synchronization with the reproduction of the song.

The input of the title is executed in step S1 in the flowchart of FIG. In this embodiment, it can be executed before the recording of a plurality of music pieces on the MD 1 is completed.
For example, the input operation of the title information of the first to third songs shown in FIG. 7 can be executed during the period when the first song is recorded on the MD1. The titles of the 4th and 5th songs are also SR
These pieces of music can be stored in the second UTOC area 4 of the AM 21 before recording. When the eject switch 28 as a recording end signal generating means is operated after the title is input, a YES output indicating the end of recording is obtained in step S2 in FIG. Next, in step S3, it is determined whether or not the last music number is equal to or larger than the number of input titles. That is, it is determined whether or not the value of the Last TNO (last song number) area 3c of the song 2 is equal to or larger than the number of titles of the song shown in FIG. If the number of songs recorded in the MD1 is three and the number of titles of the songs stored in the second UTOC area 21b of the SRAM 21 is three as shown in FIG. 7, YE is determined in step S3.
The output of S is obtained. In this case, the next step S4
In, the recording of the first and second UTOC information of the SRAM 21 on the MD1 of UTOC-0 and UTOC-1 is executed. That is, the first and second U
The data in the TOC areas 21a and 21b are transferred to the DRAM 44, and thereafter, are recorded on the MD1. On the other hand, when the output of NO indicating that the number of input titles is larger than the last music number is obtained in step S3, the deletion of the excess title is executed as shown in step S5. For example, when four songs are scheduled to be recorded on the MD 1 and the title of the fourth song is also stored in the SRAM 21 and the schedule is changed at the end of the recording of the third song and the recording of the fourth song is stopped, one more title remains. . Therefore, the excess titles on the SRAM 21 are deleted in step S5, and then the SRs are deleted in step S6.
All UTOC information of AM21 is transferred to DRAM via DRAM44.
Record in 1. When the recording of the UTOC information is completed in step S4, an ejection permission notice is generated in step S6, and the MD1 is ejected. Thus, the recording of the title ends as shown in step S7.

[0029]

[Second title recording method] The second method is the first title recording method described above.
The method is the same as the first method except that a part of the method is changed. That is, in the second method, the title recording in the second mode is selected by the mode selection switch 35, and the title recording is executed using the title area 21c of the SRAM 21 as the title memory. Is the same as Title area 2 for second method of SRAM 21
1c functions as a buffer area of the second UTOC area 21b, and is configured substantially the same as the second UTOC area 21b. That is, the title information input in step S1 of FIG. 8 is stored in the second UTOC area 21b.
Are written directly to the title area 21c. Accordingly, the comparison between the last music number and the number of input titles in step S3 in FIG. 8 is also performed based on the information in the title area 21c. Number of input titles is Last
When the TNO is larger than the last song number, only the titles from the first song to the last song number are extracted from the title area 21c and are stored in the UTOC-list of the second UTOC area 21b.
Written to 1. Thereafter, the information in the first and second UTOC areas 21a and 21b of the SRAM 21 is stored in the DRAM 21.
The data is written to MD1 via 44. Note that the second method is the same as the first method except that the title area 21c functioning as a buffer is used.
A plurality of title information can be input to the SRAM 21 without waiting for the end of recording of a plurality of music pieces in the same manner as in the first method, and the same effect as in the first method can be obtained.

[0030]

[Third Title Recording Method] The third method is the second title recording method described above.
Of the information in the title area 21c of the SRAM 21 in the second UTOC area 21b.
This method is the same as the second method except that the transfer to the tune is performed every time the recording of one song is completed instead of performing the transfer in a lump. That is, when the third method is selected by the mode selection switch 35, the transfer timing of data from the title area 21c to the second UTOC area 21b is changed. Title area 21c
Is written in accordance with the flowchart shown in FIG. 9 and FIG.
Steps that are substantially the same as those described above are given the same reference numerals, and descriptions thereof are omitted. The flowchart of FIG. 9 is the same as FIG. 8 except that new steps S11, S12 and S13 are added between steps S1 and S2 of the flowchart of FIG. 8, and steps S3 and S5 of FIG. 8 are deleted. In FIG. 9, the process returns to step S1 when a NO output indicating that recording is not completed is obtained in step S2. In the third method, it is determined whether or not the track number (song number) has been incremented as shown in step S11 of FIG. Note that there are the following first, second and third increments as increments of the music. The first increment is an increment generated by changing the “track number (song number)” as “CD sub-queue information” that can be obtained when transferring a song from a CD to an MD. The second increment is an increment that occurs when printing is manually stopped and then started again. The third increment is an increment that occurs when the silent period of the input signal from the input terminals 12 and 12a in FIGS. 4 and 6 exceeds a predetermined time. If an output of YES indicating that the track number (song number) has been incremented is obtained in step S11 of FIG. 9, the next UTOC Last-T is output in the next step S12.
The last song number of NO is read, and then, at step S13, L
The titles up to the last track number indicated by “ast-TNO” are stored in the second UT from the title area 21 c of the SRAM 21.
Move to the OC area 21b. Accordingly, in the method of FIG. 9, the second U
The title information is transferred to the TOC area 21b. Therefore, the time length from the time when the recording of the last song to the MD1 is completed to the time when the recording of the title to the MD1 is completed can be shortened. In the flowchart of FIG. 9, when it is determined in step S2 that the recording of the music has been completed based on the operation of the eject switch 28, the recording of UTOC information for the MD1 is executed in step S4. That is, SRA
M21 first and second UTOC regions 21a, 21b
Is transferred to the MD 1 via the DRAM 44.
Next, as shown in step S6, the ejection is permitted, the ejection is performed, and the recording of the music and the title is completed.

In any of the first, second and third title recording methods described above, a title can be entered without being restricted by the recording of music, and the degree of freedom in title input is increased. Therefore, an easy-to-use MD recorder can be provided.
