The information (digital audio data) of the second song reproduced by the reproducing apparatus 10 is transferred to the recording apparatus 12 via the reproducing side digital audio interface 40, the data line 14 and the recording side digital audio interface 70, and the second optical disc. Recorded at 48.

Then, as shown in S5 of FIG. 2, it is judged "is the reproduction / recording of the second music finished?", And if "YES",
Recording by the recording device 12 stops and pauses (S
6) Then, the playback device 10 makes a pausing by accessing the beginning of the fifth song (S7). Stopping and pausing based on this judgment are performed by the recording control circuit 42 and the reproduction control circuit 72.

Then, as shown in S8 of FIG. 2, "Standby OK?" Is judged, and if "YES", reproduction (reading) of the fifth music by the reproducing apparatus 10 is started and recording apparatus 12 causes the reproduction. Recording starts (S
9). The start based on this judgment is also performed by the recording control circuit 42 and the reproduction control circuit 72 as described above. Therefore, the information (digital audio data) of the fifth tune reproduced by the reproducing apparatus 10 is transferred to the recording apparatus 12 via the reproducing-side digital audio interface 40, the data line 14, and the recording-side digital audio interface 70. It is recorded on the second optical disc 48.

Then, as shown in S10 of FIG.
Is the song playback recording completed? Is determined and if "YES", recording by the recording device 12 is stopped (S11),
The recording device 12 records the lead-in information about the information of the second and fifth songs on the PMA of the second disc 48 (S12), and enters the disc completion routine (S12).
13). This disc completion routine is performed as shown in FIG.
