Abstract

(57) [PROBLEMS] To read out document data stored in a recording medium by a recording / reproducing apparatus to a document editing apparatus, rewrite the data, transfer the data to the recording / reproducing apparatus, and re-store the data. To prevent a memory mistake from occurring. When music is recorded on an MD set in an MD player, the music title stored in the MD can be rewritten by reading out the previous music title stored in the MD. The MD identification data is also read out, transferred to the tape printer 30, and stored in the document register and the identification register in the RAM. When the music title stored in the document register of the tape printer 30 is rewritten and written to the MD 11, the identification data of the MD 11 is re-transferred from the MD player 10 to match the identification data stored in the identification register. The discriminator judges the discrepancy and transfers the title of the rewritten music to the MD player 10 only when the discrepancy occurs, and stores the title in the corresponding MD 11.

FIG. 2 is a flowchart showing an MD data rewriting process in an MD player and a tape printer in which the recording medium collation method is introduced. For example, in the MD player 10, when music is recorded on the MD 11, the MD player 1 rewrites the music title stored in association with the recorded music.
When the “retransmit” key provided on the key input unit 32 of the tape printer 30 interfaced with the interface 0 is operated, the I / O
Via the O interface 40, a transfer command of the MD identification data and the document data (tune title) to be rewritten is transmitted to the MD player 10 (step A1).

Then, in the MD player 10, the MD 11
The MD identification data stored in the predetermined track and the previous music title data stored in the document data recording track corresponding to the music recording track are read out via the writing / reading unit 16, respectively. Communication control unit 1
7 to the tape printer 30 via the I / O interface 18 (steps B1, B
2).

Then, in the tape printer 30, the M
The MD identification data and the music title data to be rewritten transferred from the D player 10 are stored in a RAM, respectively.
The data is stored in the identification data register and the document data register in the memory 34 (steps A2 and A3).

The previous music data stored in the document data register in the RAM 34 is read out and displayed on the display unit 37, and the key input unit 32 is operated to operate the MD.
11 is rewritten to a music title corresponding to the newly recorded music, a retransmission command of the MD identification data is transmitted from the communication control unit 39 to the MD player 10 via the I / O interface 40 (step A4). , A
5).

Then, in the MD player 10, the MD 11
The MD identification data stored in the predetermined track is read out again and transferred to the tape printer 30 again (steps B3 and B4).

Then, in the tape printer 30, the RAM
MD already stored in the identification data register
A match / mismatch between the identification data and the retransmitted current MD identification data is determined, and it is determined whether the MD 11 set in the MD player 10 has not been replaced with a different MD (step A6). ).

Here, the MD identification data already stored in the identification data register in the RAM 34 matches the re-transferred MD identification data, and it is determined that the music title is the target MD to be rewritten. Then, the music title rewritten by the operation of the key input unit 32 is transferred to the MD player 10, and the music title recorded on the MD 11 set in the MD player 10 is rewritten (steps A6 → A7). ,
B5).

When the print key of the key input section 32 is operated in the tape printer 30, a new music title rewritten and displayed on the display section 37 is printed out on a tape in the printing section 38, and the MD title is printed out. It can be used by pasting on the MD 11 set in the player 10.

On the other hand, the RAM 3 of the tape printer 30
In this case, the MD identification data already stored in the identification data register 4 and the re-transmitted MD identification data do not match, and the MD 11 currently set in the MD player 10 is different from the MD to which the title of the music should be rewritten. If it is determined that it is another MD, an NG warning message such as "Please set a correct MD" is displayed on the display unit 37 (steps A6 to A8).

Therefore, according to the MD player and the tape printer adopting the recording medium collation method having the above configuration, when music is recorded on the MD 11 set in the MD player 10, the music is associated with the recording track of the music. To rewrite the stored song title,
At the same time as reading out the previous program title stored in D11, the MD identification data is also read out and the tape printer 3
To the document data register and the identification data register in the RAM 34. When rewriting the music title stored in the document data register of the tape printer 30 and writing it to the MD 11, the MD
11 is re-transferred from the MD player 10 to determine a match / mismatch with the identification data stored in the identification data register, and the rewritten music title is transferred to the MD player 10 only when matched. Applicable MD
11, the data can be prevented from being erroneously rewritten when the MD player 10 is set to an MD different from the target of rewriting the music.

In the recording medium collation method of the embodiment, the identification data stored in advance on a predetermined track of the MD 11 is collated at the time of data reading and at the time of data writing to determine its identity. However, when rewriting the program title to the MD 11, the tape printer 30
The random number generated on the side is stored in the MD 11 as identification data, and when writing the newly rewritten music title into the MD 11, the identification data based on the random number stored in the MD 11 is read out and collated with the generated random number. The MD
11 may be determined.

FIG. 3 shows an M player and a tape printer in which a collation method of a recording medium by random number generation is introduced.
It is a flowchart which shows D data rewriting processing. For example, in the MD player 10, when music is recorded on the MD 11, the music title stored in association with the recorded music is rewritten.
When a “retransmit” key provided on the key input unit 32 of the tape printer 30 interfaced with the player 10 is operated, random number data is generated by the random number generator 36, and the communication control unit 39 transmits the random number data via the I / O interface 40. Is transferred to the MD player 10 (step C1,
C2).

Then, in the MD player 10, the random number data transferred from the tape printer 30 is written to a predetermined track of the MD 11, and a write completion response signal is returned to the tape printer 30 (step D1). , D2).

Then, a transfer command signal of the music title stored in association with the music data recorded in the MD 11 is output from the tape printer 30 to the MD player 10, and the MD player 10 stores the transfer command signal in the MD 11. The title of the current song is read and transferred to the tape printer 30 (steps C3, D3, D
4).

Then, in the tape printer 30, the M
The program title data to be rewritten transferred from the D player 10 is stored in the document data register in the RAM 34 (step C4).

Then, the previous music data stored in the document data register in the RAM 34 is read and displayed on the display unit 37, and the key input unit 32 is operated to operate the MD.
11 is rewritten to a music title corresponding to the newly recorded music, a command to transfer random number data stored in a predetermined track of the MD 11 to the MD player 10 from the communication control unit 39 via the I / O interface 40. Is transmitted (steps C5 and C6).

Then, in the MD player 10, the MD 11
Is read out and transferred to the tape printer 30 (steps D5 and D6).

Then, in the tape printer 30, the random number data already generated by the random number generator 36 in step C1 and transferred to the MD player 10 and the MD
Match with random number data transferred from player 10 /
A mismatch is determined, and it is determined whether or not the MD 11 currently set in the MD player 10 has been replaced with a different MD (step C7).

Here, the random number data already generated by the random number generator 36 and the random number data transferred from the MD player 10 match, and it is determined that the music piece title is the target MD to be rewritten. Then, the music title rewritten by the operation of the key input unit 32 is transferred to the MD player 10, and the music title recorded on the MD 11 set in the MD player 10 is rewritten (steps C7 → C8). , D
7).

On the other hand, the random number data already generated by the random number generator 36 of the tape printer 30 does not match the random number data transferred from the MD player 10, and the MD currently set in the MD player 10
If it is determined that 11 is another MD different from the MD whose track title should be rewritten, an NG warning message such as "Please set a correct MD" is displayed on the display unit 37 (step C7). → C9).

Therefore, according to the MD player and the tape printer adopting the recording medium collation method based on the random number generation, it is not necessary to record predetermined identification data in the MD 11 in advance. Each time, random number data is generated by the tape printer 30 and stored in the MD 11 as identification data.
By comparing the random number data read from the MD 11 with the generated random number data at the time of recording the actual rewrite data, it is possible to determine the identity of the MD 11 that requires data rewrite.

In the collation method of the recording medium according to each of the embodiments, the identification data stored in a predetermined track of the MD 11 is collated, or the random number data generated each time data is rewritten and stored in the MD 11 is collated. In this case, the identity of the MD at the time of data reading and at the time of writing is determined. However, upon rewriting the title of the music to the MD 11, the total value of the data read from the MD 11 is counted, and the newly rewritten music is counted. Title the MD1
When writing to MD1, the total value of the data read and counted again from the MD 11 may be compared with the total value of the already counted data to determine the identity of the MD 11.

FIG. 4 is a flow chart showing the MD data rewriting process in the MD player and the tape printer in which the collation method of the recording medium by the collation of the total data value is introduced.

For example, in the MD player 10, MD1
In order to rewrite the music title stored in association with the recorded music when the music is recorded on the tape player 1, the key input unit 32 of the tape printer 30 interfaced with the MD player 10 is provided. When the "Resend" key is operated, the tape printer 30
Is transmitted from the communication control unit 39 to the MD player 10 via the I / O interface 40 (step E1).

Then, in the MD player 10, the MD 11
The previous song title data stored in the document data recording track corresponding to the music recording track is read out via the writing / reading unit 16 and is transmitted from the communication control unit 17 via the I / O interface 18. Data is transferred to the tape printer 30 (steps F1 and F2).

Then, in the tape printer 30, the M
The total data value of the previous title data transferred from the D-player 10 is counted and stored in the work area in the RAM 34, and the title data itself is stored in the document data register (step). E2, E3).

The previous music data stored in the document data register in the RAM 34 is read out and displayed on the display unit 37, and the key input unit 32 is operated to operate the MD.
11 is rewritten to a music title corresponding to the newly recorded music, a re-transfer instruction of the music title data stored in the MD 11 is transmitted from the communication control unit 39 to the MD player 10 via the I / O interface 40. It is transmitted (steps E4 and E5).

Then, in the MD player 10, the MD 11
The previous title data stored in the document data recording track corresponding to the music recording track is read out again and transferred to the tape printer 30 again (steps F3 and F4).

Then, in the tape printer 30, the RAM
A match / mismatch between the total data value of the MD 11 already stored in the work area 34 and the current total data value of the retransmitted MD is determined and set in the MD player 10. It is determined whether or not the MD 11 has been exchanged for a different MD (step E6).

Here, the total data value of the MD 11 already stored in the work area in the RAM 34 matches the total data value of the retransmitted current MD side, and the title of the music piece should be rewritten. When it is determined that the MD is the target MD, the music title rewritten by the operation of the key input unit 32 is transferred to the MD player 10, and the MD set in the MD player 10 is set.
The song title recorded in No. 11 is rewritten (steps E6 → E7, F5).

On the other hand, the RAM 3 of the tape printer 30
In this case, the total data value of the MD 11 already stored in the work area 4 does not match the total data value of the re-transferred current MD, and the MD 11 currently set in the MD player 10 is If it is determined that the MD is different from the MD whose title should be rewritten, an NG warning message such as "Please set a correct MD" is displayed on the display unit 37 (steps E6 to E8). ).

Therefore, according to the MD player and the tape printer adopting the recording medium collation method based on the collation of the total data value, it is necessary to record predetermined identification data on the MD 11 in advance, and it is necessary to generate the identification data every time. There is no need to store the random number data as identification data.
By counting the total data value stored in the MD 11 and comparing the data value at the time of reading and writing the MD data, it becomes possible to determine the identity of the MD 11 requiring data rewriting.

Further, in each of the above-described embodiments, in the relationship between the MD player 10 and the tape printer 30, the MD 1
1 describes the case where audio data and its associated document data are stored, but the data stored in the MD 11 may be image data and its associated document data, and the relationship between the recording / reproducing device and the document editing device is as follows. The MD
The relationship between the DAT player and the tape printer or the word processor is not limited to the relationship between the player 10 and the tape printer 30.
