[0017]
The operation of the recording apparatus configured as described above will be described below based on the flowchart shown in FIG.
[0018]
First, it is determined whether or not the recording pause key is turned on (step S1). If turned on, the process proceeds to step S2 to enter a normal recording pause state. In step S3, the channel status bit detector 23 starts reading control signals such as sampling frequency and copyright protection information. Next, it is determined whether or not the specific track recording key is turned on (step S4) and whether or not the normal recording key is turned on (step S5). The normal recording pause state is maintained until it is turned ON. When the normal recording key is turned on, the process proceeds to step S6, where a normal recording command is output, and the input audio signal is recorded in the MD under predetermined control according to the command of the system controller 16. This recording state is continued until the stop key S6 is turned on.

If it is determined in step S4 that the specific track recording key has been turned ON, the process proceeds to step S8, where the specific track recording pause state is entered, and the user data bit detection unit 24 performs sub-checking from the digital audio signal input to the digital signal input circuit 19. Input the code signal. Then, the track number included in the subcode signal of the digital audio signal input by the track number detecting unit 25 is detected, and the track number is a specific track number, that is, a specific track number stored in the specific track memory 26 in advance. Whether the track number is a specific track number, the process proceeds to the next step S10. Here, it is determined whether there is sound from the level detected by the level detection unit 22 that detects the level of the input digital audio signal. If it is determined that there is sound, the process proceeds to step S11 to record a specific track number. Then, the audio signal of the specific track number is recorded.
[0020]
Next, in step S12, it is determined whether or not the input of the signal of the specific track number started based on the recording command in step S11 is continued. In the next step S13, it is determined whether or not there is an audio signal. In this case, if the stop key is not turned on in step S14, the process returns to step S12, and the determinations from step S12 to step S14 are repeated, and recording of the digital audio signal of the specific track number is continued here. When the stop key is turned ON during recording of the digital audio signal of the specific track number, the process proceeds from step S14 to step S15, the system controller 16 outputs a stop command, and recording is stopped by predetermined control. Return to S1.
[0021]
If it is determined that the track number is not a specific track number in step S9 described above, or if it is determined in the next step S10 that there is no sound even in the signal of the specific track number or the level is low, the process proceeds to step S16. If the stop key is not turned on, the process returns to step S9 and the same determination is repeated. If it is determined in step S16 that the stop key is ON, the process proceeds to step S15 and a stop command is output.
[0022]
Next, if it is determined in step S12 that the specific track number is no longer used, or if it is determined in the next step S13 that there is no sound even if the signal of the specific track number is low or the level is low, the recording ends. If it is determined that the digital audio signal of the specific track number to be input next is recorded, the specific track recording pause setting state is set. That is, in this state, for example, if recording is performed from CD to MD, recording of a specific track (for example, the first song) of one CD is completed, and then the next CD is reproduced to specify the CD. It is a pause state waiting to record a track.
