n Modulation) / ACIRC (Advan
ced Cross Interleave Reed
-Solomon Code) Modulation and demodulation circuit A8. The address decoder A6 detects and decodes the address information superposed on the CLV control sine wave signal that causes the guide groove preformed in the MD (A) 1 to meander by a slight amount. This output is applied to the EFM / ACIRC modulation / demodulation circuit A8. The EFM / ACIRC modulation / demodulation circuit A8 demodulates the EFM and ACIRC, and the output thereof is input to the memory controller A10.

The memory controller A10 is an EFM / A

The data read out from the storage circuit 9A is output to the transmission circuit 12, and the transmission circuit 12

The system controller (master controller) 11 is used for command signals for controlling the reproduction operation of the master section, the search operation of the optical pickup, etc., and the MD.
(A) 1 has a function of transmitting a detection signal such as address information, and is connected to each unit of the servo control circuit A7, EFM / ACIRC modulation / demodulation circuit A8, and memory controller A10 via a bus to receive and transmit control data.

The system controller 11 controls an operation unit 13 for inputting various command signals and the like to the system controller 11 with an input device unit, and a display unit 14 for displaying various data from the system controller 11. The system controller 11 also functions as a controller of the slave unit. The system controller 11 communicates each command to the system controller (slave controller) 16 to control the slave. The instruction from the operation unit 13 is input to the system controller 11.

When an instruction to record the table of contents is issued from the operation unit 13, the system controller 11 confirms the preparation for transferring the table of contents information to the first memory controller A10 and sends a control signal to the system controller 16.
Then, when the system controller 11 receives the preparation signal for receiving the table-of-contents information from the system controller 16, the system controller 11 sends a signal indicating whether all the table-of-contents information is transferred from the transmission circuit 12 or only predetermined table-of-contents information is transferred. Send to the memory controller A10.

Next, the slave section will be described. The receiving circuit 15 receives the compressed data sent from the transmitting circuit 12 of the master unit, and stores the compressed data in the memory circuit B23 via the memory controller B22. When the amount of data stored in the memory circuit B23 reaches a predetermined amount,
The data is recorded on the MD (B) 20.

That is, the memory controller B22 reads out the data stored in the memory circuit B23, and the EFM / AC
Output to the IRC modulation / demodulation circuit B26. EFM / ACI
The RC modulation / demodulation circuit B26 performs EFM and ACIRC modulation and outputs the result to the head drive circuit 18, and the head drive circuit 1
Reference numeral 8 drives the recording head 17 to generate magnetic fields of N and S poles corresponding to the recording EFM signal, and the magnetic field is applied to the MD (B) 20.

On the other hand, from the optical pickup B19 arranged on the opposite side to the MD (B) 20, a high power laser output via the servo control circuit B7 'in response to a command from the system controller 16 including a microcomputer. Is irradiated on the MD (B) 20. MD (B) 20
The magnetic field from the recording head 17 that sandwiches the magnetic field and the laser beam from the optical pickup B19 are interlocked, and MD (B)
A recording signal is recorded at 20.

Next, the copy source MD (A) 1 is added to the master section.
Will be described, and the operation when the duplication destination MD (B) 20 is inserted into the slave unit to perform duplication will be described. FIG. 2 is a conceptual diagram of a radial cross section showing a recording state of the MD inserted in the master portion from the side surface of the disc. In this case, since a plurality of small block data consisting of continuous areas are present on the MD in a dispersed manner on one MD, one track is composed of a plurality of recording signal parts. (Structure information) is recorded in the UTOC area 1E as table-of-contents information. A, B, ..., I shown in FIG. 2 indicate a start position address or an end position address of each recording signal part.

FIG. 3 is a table showing the recording state of the recording signal part shown in FIG. The table of contents information of each track (song) in the aforementioned UTOC area is shown. 2 and 3, the track 1 is composed of a recording signal part B1 which starts at the start position address A and ends at the end position address B, and a recording signal part B3 which starts at the start address E and ends at the end address F. It is configured. Therefore, the reproduction order of the track 1 is first the recording signal part B1 and then the recording signal part B3. Track 1 ends at address F of recording signal part B3. Therefore, the track 1 is composed of two recording signal parts.

The track 2 has a recording signal part B2 which starts at the start position address C and ends at the end position address D.
And a recording signal part B4 which starts at the start address G and ends at the end address H. Therefore, the reproduction order of the track 2 is first the recording signal part B2 and then the recording signal part B4. Track 2 ends at address H of recording signal part B4. Therefore, track 2
Is formed from two recording signal parts. Also,
In the information of the UTOC area 1E, information used when recording another track (song), that is, information 33 of a recordable area is recorded and registered. The master section is not involved in the information 33 on the recordable area.

The link information 31 and 32 of each track and the recordable area information 33 described above are read by the system controller 11 of FIG. 1 and used at the time of reproduction. 4 and 5, the MD to be recorded inserted in the slave unit.
The recording state of was shown. FIG. 5 is a table of the recording state of the recording signal part shown in FIG. UTOC area 1E
The table of contents information of each track (song) is shown.

In FIGS. 4 and 5, the track 1 is composed of a single part of the recording signal part B1 which starts at the start position address A and ends at the end position address B. Then, as the information 52 of the later recordable area,
It is recorded and registered that the area after the address C is a recordable area. As will be described later, the information 52 of the recordable area is used by the system controller 16 (slave controller) of FIG. 1 that controls the slave unit during copying.

Next, the MD (A) inserted in the master unit
2 is recorded in two tracks as shown in FIGS. 2 and 3, and the operation when the first and second tracks are copied to the MD (B) 20 of the slave section will be described.
The MD (B) 20 inserted in the slave portion has already been recorded on one track, but according to the method of the present invention, the MD (B) 20 can be duplicated in addition to this recording state.

FIG. 8 is a flow chart showing the operation of the recording processing method of the recording apparatus according to the present invention. In the master section, in order to transmit the table-of-contents information of the master disk MD (A) 1 of the copy source mounted in the master section to the slave section, reading of the table-of-contents information of MD (A) 1 by the optical pickup 3A is started ( S1).

Then, while the table of contents information is being read, the storing operation in the memory circuit A9 is started (S2). This is because all the subsequent information on the master unit side is transmitted to the slave unit so that the slave unit can perform the process related to the duplication. Since the slave unit can perform the process related to the duplication, even when a plurality of slave units are connected to one master unit, the duplication can be completed almost at the same time.

The table of contents information includes track configuration information,
The year and date information of track recording, the disc name of MD and the name of track are also included, but all of them are transmitted from the master section to the slave section. The system controller 11 transmits a control signal indicating a reception preparation command for the table of contents information to the system controller 16 (S3).

Slave system controller 16
Is the copy source disc MD transmitted from the master unit.
(A) In order to receive the table of contents information of 1 and store it in the memory circuit B23, the memory controller B2 is prepared to store the transferred table of contents information. Then, the system controller 16 sends a reception preparation completion signal to the system controller 11. System controller 11
When receiving the reception preparation completion signal (Y in S4), instructs the memory controller A10 to send out the table-of-contents information from the transmission circuit 12 (S5).

Upon receiving the instruction signal from the system controller 11, the memory controller A10 sends out the table-of-contents information to the transmission circuit 12. The table of contents information is received by the receiving circuit 15 of the slave unit and stored in the memory circuit B23 via the memory controller B2 (S6). When the table of contents information is stored in the storage circuit B23, the data is subsequently sent from the transmission circuit 12 (S7) and stored in the storage circuit B23 (S8). At this time, in the slave unit, the system clock signal included in the signal from the transmission circuit 12 of the master unit is received by the reception circuit 15 and used as a clock signal for data reception operation.

The output timing of the data transmitted by the transmission circuit 12 is synchronized with the system clock of the master section.
This is because the received data cannot be normally received unless the slave unit receives the audio data in synchronization with the system clock of the master unit. That is, the master unit can continuously transmit the transmission data at the timing of the system clock on the master unit side.

On the other hand, for example, when data is transferred by the handshake method of the master unit and the slave unit, in a system in which a plurality of slave units are connected, a handshake is performed for each slave unit to transfer the data. There must be. Therefore, data exchange becomes complicated and the duplication process takes time. The data stored in the memory circuit B23 is read by the memory controller B22 (S9) and recorded in the MD (B) 20 (S1).
0). The process is repeated until data recording is completed (Y in S10).

The signal to the transmission circuit 12 in the master section is
It is an output only signal. Conversely, the receiving circuit 1 in the slave section
The signal to 5 is an input only signal. As an example, FIG. 10 shows a memory layout diagram of the storage circuit B23 of the slave unit in which the audio data received by the reception circuit 15 is stored. From the lower part of the address part, the copy destination M installed in the slave part
An area 91 in which the table of contents information of the D (B) 20 is stored is arranged.

In other words, this is the table of contents information area of the slave unit itself. Next to the end address of area 91, the copy source MD (A) transferred from the master section
An area 92 for storing the first table of contents information is arranged.
Subsequently, an area 93 for storing the data to be recorded transmitted from the master unit is arranged above the area 92.

When the slave section is ready to receive the table-of-contents information, the master section sends the table-of-contents information to the transmission circuit 12. The transmitted table of contents information is received by the receiving circuit 15,
In accordance with a command from the system controller 16, the memory controller B22 causes the copy source MD shown in FIG.
(A) It is stored in a predetermined area 92 for storing the table of contents information of 1.

Next, by communication between the system controller 11 of the master section and the system controller 16 of the slave section, the copy destination MD (B) 20 mounted in the master section.
The information of the track number is sent from the master section to the slave section. In this embodiment, the numbers of track 1 and track 2 are transmitted to the system controller 16. After the table-of-contents information and the track number to be duplicated are transferred to the slave unit, the process proceeds to a process of transmitting and receiving data to be recorded.

The master unit stores the compressed data from the disk address corresponding to the first track of MD (A) 1 from the address A shown in FIG. 2 and the data obtained by compressing the audio signal in the memory circuit A9. Also, the system controller 1
1 gives an instruction to the system controller 16 for a preparation operation for a duplication operation. After receiving the instruction of the preparation instruction, the system controller 16 of the slave unit uses the optical pickup B19 at the disc address C shown in FIG. 4, which is the next recordable head address of the MD (B) 20 inserted in the slave unit. To move. Furthermore, the memory controller B2
2 is set in a state in which the transferred data can be stored. The received data is stored in area 93.

When the replication preparation operation on the slave is completed,
The system controller 11 recognizes this state by communicating with the system controller 16. After the slave unit is ready for replication, the master unit sends the reception completion control signal received by the system controller 11 to the memory controller A10. In this way, the transmission circuit 12
Memory controller A1 for transferring compressed data to
0 is set in a state in which compressed data can be read from the memory circuit A9.

Thereafter, the compressed data is read out and transmitted while controlling the memory controller A10 so that the transmission amount of the compressed data from the transmission circuit 12 does not exceed the storage amount of the compressed data from the MD (A) 1. Output to the circuit 12. When the reading of the compressed data reaches the disc address B of the first track in FIG. 2, the optical pickup A is moved to the head address E of B3 which is the next recording part.
3 is moved and storage of compressed data in the memory circuit A9 is restarted in the same manner. Even during this operation, the output of the transmission circuit 12 for data transfer to the slave unit is continuously performed.

In the slave unit, the data is stored in the memory circuit B23 via the transmission data receiving circuit 15 from the data transmitting circuit 12 of the master unit and further via the memory controller B22. In the slave unit, when the storage amount in the storage circuit B23 reaches a predetermined amount, the MD of the copy destination
(B) The compressed data is recorded in 20. Here, the predetermined amount is
In the case of MD, it corresponds to one cluster. When a normal MD is reproduced, the audio time of one cluster corresponds to a real time of 2.04 seconds. In this way, recording on the MD (B) 20 is repeated every time a predetermined amount of data is stored in the memory circuit B23.

The duplication time will be described. Although one cluster takes 2.04 seconds in real time when the compressed data is expanded, the time required for the master unit to store the compressed data corresponding to this one cluster in the memory circuit A9 is M.
In the case of D, it is about 500 milliseconds and can be stored in a quarter of the real time. Here, the real time is a time length when the compressed data is expanded.

In this embodiment, it takes about 1 to transfer compressed data corresponding to one cluster from the master section to the slave section.
Requires 00 ms. In the master section, MD (A)
Storage from 1 to the storage circuit A9 and transmission of data to the slave unit are performed in parallel. Therefore, if the data transmission speed and the storage speed are almost the same, it is possible to transmit at the storage speed to the memory circuit A9 in the master unit.

Therefore, even an MD in which 74 minutes of music data is recorded can be duplicated in a quarter of that time, that is, in about 18 minutes. As shown in FIG. 2, since the track 1 is divided into the recording signal part B1 and the recording signal part B3, the optical pickup A3 moves to move from the disk address B to the disk address E.
Therefore, the operation of storing the compressed data in the memory circuit A9 cannot be continuously performed. If this search time is available, the duplication time will not be reduced to a quarter of the time, and the duplication time will increase, but duplication can be done in a maximum of one-third of the time.

As described above, after the compressed data storage operation in the memory circuit A9 is completed up to the disk address F of the recording signal part B3 of the track 1 in the master section, the storage of the compressed data of the track 1 is completed. , Then track 2
The optical pickup A3 is moved to the start disc address C of B2 which is the first recording signal part of the same, the data is read from the MD (A) 1 in the same manner, and the storage circuit A
9 and the reading of compressed data from the memory circuit A9 for data transmission to the slave unit is repeated.

When the storage and transmission of the compressed data up to the end disk address H of track 2 are completed, the transfer of the compressed data from the master unit to the slave unit is completed. In the slave unit, the received compressed data is MD at almost the same time.
(B) Since the data is recorded in 20, the recording of the compressed data is completed 2 to 3 seconds after the data transmission of the master part is completed.

As described above, after recording on the MD (B) 20 in which the track 1 and the track 2 of the duplication source MD (A) 1 inserted in the master section are inserted in the slave section (Y in S10). ) Next, the slave unit edits and generates the table-of-contents information of the track recorded in the MD (B) 20 (S1).
1), the table of contents information is recorded in MD (B) (S12). M
If the D (B) 20 is an unrecorded disc, the storage circuit B
The table of contents information stored in 23 is stored in the memory controller B2.
Read it in 2 and record it without editing.

FIG. 9 shows a flow chart for creating the table-of-contents information of the track according to the present invention. First, M recorded in the slave section
The table-of-contents information (UTOC) in which the recording area of the D (B) 20 is the second track is created (ST1). The data from the master part has been transferred for two tracks (the first track and the second track of the copy source MD (A) 1), but the table of contents information (start and end addresses) is a single track.
Create Specifically, this is an area obtained by adding the first track and the second track of the copy source MD (A) 1 copied from the master section. Since the first track has already been recorded in the duplication destination MD (B) 20 inserted in the slave section, the track recorded here is used as the second track.

This is shown in the conceptual diagram of FIG. 6 showing the state in which the tracks from the master section to the slave section are duplicated. Address C
In this area, the contents from the address C to the address D are recorded, and the table-of-contents information having the recording signal part from the address C to the address D as the second track is created. The net time of the track corresponding to the address C to the address E is the total time of the first track and the second track of the MD mounted on the master unit in FIG. That is, FIG.
Is the total of the recording areas from addresses A to H.

Next, the copied track is divided into
Create table of contents information for track and track 3. This table of contents information is the copy source MD (A) attached to the master unit.
It is created using the first table of contents information (UTOC). That is,
Since the duplicated tracks are the first and second tracks of the duplication source MD (A) 1, the second track of the slave section created in step ST1 is the playing time of the first track.
A second track and a third track can be created by dividing the track. The performance time of the first track, which is the point here, can be calculated by the slave controller 17 reading the table of contents information 92 of the master section in FIG.
The procedure of dividing with the calculated playing time is similar to the case of dividing one track into two tracks.

In this embodiment, if the track is divided only once, the process ends. For example, when 100 tracks are duplicated, if the last track of the slave section is divided 99 times, that is, the number of duplications is n (n-
1) You can create the necessary table of contents information by dividing it once. The points to be divided are the playing time of track 1 and track 2 in that order.
The playing time of, the playing time of track 3 ...

The divided playing time can be obtained by communication from the master section to the slave section, but in the present embodiment, processing is performed by the slave section instead of duplication processing while communicating. I chose Therefore,
In a system in which a plurality of slave units are connected to one master unit, it is possible to reduce an increase in processing load of the master unit, which is caused by communication from the master unit to each slave unit.

This method can also be used when duplicating the track name and the additional information data added to the track of the recording date / time information. If the above dividing process is shown in FIG. 6, the dividing points are addresses D and E, and the second track created in step ST1 is divided into two tracks, a second track and a third track. Here, the address D and the address E are consecutive disk addresses.

In the case of the MD, since information such as a track name can be added, the table of contents information of the master section is read, the presence or absence of the name information is checked, and the MD ( B) Used for 20. If there is the name of the first track of the duplication source MD (A) 1 inserted in the master part, it is duplicated in the second track name of the slave part, and is also the duplication source MD (A) 1 inserted in the master part.
If there is a name of the second track of the above, it is copied to the third track of the slave section (ST3).

In the duplication step of the disc name, similarly to step ST3, if the disc name is recorded in the master portion, it is duplicated in the slave destination MD (B) 20 (ST4). Here, copy the disc name,
If this is not done intentionally, there is no problem if this step is not performed. As in this example, when the duplication destination MD (B) 20 inserted in the slave portion has already recorded the first track, it is better not to duplicate.

Next, the recording date and time information of the track is duplicated (ST5). This is also the same as the duplication of the track name in step ST3. If the recording date and time information is recorded in the MD (A) 1 of the master unit, it is duplicated. Next, the recording date / time information of the disc is duplicated (ST6). Processing is performed in the same way as step ST5. Step ST4
Perform the same process as the step of copying the disc name of. If you do not want to name the disc, skip this step.

Next, the copy destination MD of the copied slave unit
(B) Information of 20 track modes of the second and third tracks is created (ST7). This track mode information is the second track of the master section composed of emphasis information, monaural / stereo information, copyright information, etc., and this track mode information of the third track is the copy source MD (A) 1 of the master section. The table of contents information is transferred to the slave unit, and the information is duplicated in the slave unit. Also, since this track mode information may change within one track, this is also duplicated.

In this embodiment, there is no change in the track mode within the track for both the first track and the second track of the copy source MD (A) 1. When there is a change, the number of recording signal parts increases. As described above, the table-of-contents information of the second and third tracks of the MD (B) 20 duplicated in the slave section is created. FIG. 7 is the table-of-contents information after the UTOC data of the copy destination MD shown in FIG. 6 is created. Figure 7
The recording signal part B2 indicated by 72 becomes the second track and starts from the address C in FIG. 6 and ends at the address D. Similarly, the recording signal part B3 shown at 73 in FIG.
It becomes the third track, starting from address E in FIG. 6 and ending at address F.

By the way, the recording signal part is divided into two as shown in FIG. 3 for both the first track and the second track which are the tracks of the copy source MD (A) 1. This is because it was created by editing or the like. Considering this state in FIG. 2, when reproducing the first track, after the address B of the recording signal part B1, the address B is recorded on the disc.
The optical pickup A3 must be moved to the address E away from.

At this time, if a servo error occurs due to vibration or the like and there is no compressed data in the memory circuit A9 for outputting voice, the voice being output is interrupted. That is, when there are a plurality of recording signal parts such as the first track and the next recording signal part connected to them is at a distant disk position, a search time is required, so that compressed data is stored in the storage circuit A9. The storage must be stopped once. Therefore, the compressed data storage circuit A9
This search time will rob you of the opportunity to store.

However, in the present embodiment, the second track and the third track of the copy destination MD (B) 20 are recorded in the continuous area of the MD (B) 20, and one Since the recording signal part is completed, the recording signal part search time can be omitted.

In the case of the MD format, in order to protect the sound interruption of the audio output, even if a plurality of recording signal parts exist in one track, the leading recording signal part and the ending recording signal part are excluded. , The length of the intermediate recording signal part is defined as 4 clusters or more. Due to this regulation, when the length of the intermediate recording signal part is less than 4 clusters, further editing, specifically, track division and track connection cannot be performed.

However, in this embodiment, the second track and the third track of the MD (B) 20 which is the duplication destination of the slave part are recorded in the continuous area of the MD (B) 20, and one recording is made. It can be completed in the signal part. Therefore, it is possible to record and provide the MD from which the above-mentioned restrictions are removed. After the table-of-contents information of the track in FIG. 9 is created, these pieces of information are recorded in the UTOC area of the MD. When the recording in the UTOC area is completed, the entire duplication operation is completed.

In this embodiment, all of the first and second tracks of the copy source MD (A) 1 are copied, but it is also possible to copy only the selected track. Also, the slave disk that is duplicated at one time is
However, in another embodiment, a system in which a plurality of slave units are connected is possible. In this case, a plurality of slave units on the right side of FIG. 1 are prepared, and the receiving circuits of the plurality of slave units are connected to the transmitting circuit 12 of the master unit by the same line. The master unit and the slave unit can also be configured by connecting the system controller 16 of the master unit and the slave unit.

System controller 11 of the master section
In order to control a plurality of slave parts, if data transmission / reception is managed by ID numbers of the plurality of slave parts, the data can be recorded on a disk of a predetermined slave part. In addition, even if the duplication source MD track to be selected and duplicated is a track recorded at a physically distant position,
It is possible to duplicate as organized tracks. Therefore, it is possible to provide an MD in which recording signals of less than 4 clusters can be divided and connected again for editing during reproduction.
