4 and 4 are provided.

Next, the operation of this embodiment will be described with reference to FIGS. (Multi-CD player side) First, the multi-CD player 50
The system controller 52 of the memory 5 stores the program data as the reproduction order data input from the operation unit 51 in the memory 5.
No. 3, and the reproduction order is rearranged so that the music information recorded on the same CD is continuously reproduced based on the input program data, and stored in the memory 53 as actual reproduction order data (step S11). ). Specifically, as shown in FIG. 5A, the input program data is as follows: first song of disc # 1 → fifth song of disc # 2 → third song of disc # 3 → second song of disc # 2 → Disk # 1
5B, the first song of the disc # 1 → the second song of the disc # 1 → the fifth song of the disc # 2 → the second song of the disc # 2 → the disc # 3, as shown in FIG. 5B.
As in the third song, the music information of the same disc is rearranged in the reproduction order so that the actual reproduction order data is obtained. In this case, since the TOC information of the CD is recorded on the inner circumference side of the CD, if the reproduction order is rearranged so that the tracks recorded on the inner circumference side of the disc are reproduced first, the search time can be further increased. And the dubbing time can be further shortened.

Next, the system controller 52 of the multi-CD reproducing apparatus 50 inputs program data (MD reproducing order information) as shown in FIG. 5A to the MD recording / reproducing apparatus 100 via the control signal line 71. To send. (Step S12). (MD Recording / Reproducing Device Side) When the system controller 10 of the MD recording / reproducing device 100 receives the program data via the control signal line 71, it records it in the memory 54 (step S21). (Multi-CD player side) Next, system controller 5
2 transmits a recording start signal via the control signal line 71, starts reproduction based on the actual reproduction order data (step S13), and outputs the reproduction signal via the output signal line 70 to the MD recording / reproducing device 100. Output to. In the case of the above-described example, first, the first song → the second song of the disc # 1 is reproduced, the disc is changed, and the disc # 1 is replaced with the disc # 2. After the exchange, the second to fifth songs of the disc # 2 are reproduced, the disc is changed, and the disc # 2 is exchanged with the disc # 3. After the replacement, the third piece of the disc # 3 is reproduced. In this case, if a signal for suspending the recording of the MD recording / reproducing apparatus 100 is transmitted via the communication line at the time of disc change and a signal for restarting the recording after the exchange is transmitted, the disc change in the MD 20 is performed. Since the non-recorded part is eliminated, more information can be recorded in the MD 20. (MD Recording / Reproducing Device Side) Next, when the system controller 10 of the MD recording / reproducing device 100 receives the recording start signal via the control signal line 71, it starts recording the reproduction signal input via the output signal line 70. Yes (step S2
2). At the same time, the system controller 10 monitors whether or not a reproduction end signal is transmitted from the multi-CD reproduction device 50 side via the control signal line 71 (step S).
23). (Multi-CD player side) System controller 52
Determines whether or not all the reproductions are completed based on the actual reproduction order data (step S14), and when the reproductions are completed, transmits a reproduction end signal through the control signal line 71 (step S15). .. (MD recording / reproducing apparatus side) The system controller 10
By receiving the reproduction end signal through the control signal line 71, it is determined that the recording is completed (step S23),
Further, based on the program data received via the control signal line, the music order information is transmitted to the user TOC (not shown) of the MD 20.
(Step S24), and the process ends. This allows the MD recording / reproducing apparatus 100 to perform the MD after the dubbing.
When 20 is reproduced, the music information is reproduced in the order corresponding to the program data.

As described above, according to this embodiment,
It is possible to shorten the dubbing time and create an MD capable of reproducing music information in a desired order from music information of a plurality of CDs.

In the above embodiments, only the CD was described as the recording medium of the copy source, but it is also possible to use another recording medium, for example, a recording medium such as DAT, R-CD, MD. Is. Further, although only the MD is described as the recording medium of the copy destination, it is also possible to use another recording medium which is randomly accessible and writable, for example, a recording medium such as an R-CD or a phase transition type optical disk. Is.

Further, in the above embodiment, the reproducing apparatus of the copy source (multi-CD reproducing apparatus) and the recording apparatus of the copying destination (MD recording / reproducing apparatus) are provided separately, but the reproducing apparatus and the recording apparatus are provided. It is also possible to provide so as to be integrated. In this case, if the same system controller is used to control the dubbing, it is not necessary to provide the above-mentioned control signal line.
