Next, recording, that is, dubbing of digital data of a CD to an MD will be specifically described. For example, the CD changer 1 and the MD changer 6 are equipped with three CDs and MD, respectively, and the first CD has 5 CDs.
It is assumed that digital data of seven songs is recorded on the second CD and six digital data items are recorded on the third CD.

At the time of the above dubbing, first, the user
By operating the recording switch of the D changer 6, the recording operation of the MD changer 6 is started. After that, the user
By operating the reproduction switch of the D changer 1, the reproduction operation of the CD changer 1 is started. Thereby, the reproducing unit 2 of the CD changer 1 reproduces the five digital audio data recorded on the first CD as digital audio signals in order from the first one, and at this time, the first one The subcode data recorded on the CD is also reproduced as a subcode signal.

Each digital signal reproduced in this manner is input to an ATRAC encoder 9 via a digital cable, and a sub-code signal of the input digital signal is encoded and input to a microcomputer 12, and the Based on the code signal, the microcomputer 12 detects that the track number in the subcode data increases to 1, 2, 3, 4, and 5. The digital signal input to the ATRAC encoder 9 is encoded while being compressed, output to the DRAM 8, and written as digital data in the DRAM 8. The writing speed is controlled by the microcomputer 12 via the memory controller 10. Controlled.

The digital data written in the DRAM 8 is read out and converted into a digital signal by the recording unit 7.
And is output by the recording unit 7 as digital data.
It is recorded on the MD at the recording / reproducing position. In addition, DRAM
The reading speed of the digital data from the memory 8 is controlled by the microcomputer 12 via the memory controller 10.

When the reproduction of the last fifth tune of the first CD is completed, the CD changer 1
Operates the change unit 3 to change the first CD at the playback position to the second CD, and converts the digital audio data of seven songs recorded on the second CD to the first first song. , And at this time, the subcode data recorded on the second CD is also reproduced as a subcode signal.

Accordingly, in the MD changer 6, the microcomputer 12 detects that the track number has changed from 5 to 1, that is, the second track number 1 from the input subcode signal. The change unit 11 is operated to change the first MD at the recording / reproducing position to the second MD.
Then, the digital data of the second CD is recorded. During the change of the MD, the microcomputer 12 controls the DRAM 8 via the memory controller 10 to stop the output from the DRAM 8 to the recording unit 7, and
It is assumed that the digital data is fetched into the RAM 8 (stored). When the change of the MD is completed, the output from the DRAM 8 to the recording unit 7 via the memory controller 10 is resumed by the microcomputer 12.

When the reproduction of the last seventh tune of the second CD is completed, the CD changer 1 changes the second CD at the reproduction position to the third CD in the same manner as described above. The digital audio data for the six songs recorded on the third CD is reproduced as digital signals in order from the first song, and the subcode data recorded on the third CD is Play as a signal.

As a result, the microcomputer 12 of the MD changer 6 detects that the track number of the subcode data has changed from 7 to 1, that is, the third track number 1, so that the MD changer, as described above, The second MD at the recording position is changed to the third MD, and the digital data of the third CD is recorded on this MD. During the change of the MD, the output from the DRAM 8 to the recording unit 7 is stopped in the same manner as described above, and when the change is completed, the output from the DRAM 8 to the recording unit 7 is restarted.

When the reproduction of the digital data of the third CD is completed as described above, the microcomputer 4 stops the reproduction operation of the CD changer 1. At this time, since there is usually a portion on the third MD where digital data has not yet been recorded and recording is possible, the CD
After the reproduction operation of the changer 1 is stopped, the user operates the recording switch of the MD changer 6 and
Is stopped, and dubbing ends.

In the above embodiment, the changer for reproduction is a CD changer, but may be an MD changer or the like.
