An audio signal recording apparatus is constructed to record a track number signal which allows the recording of an index number signal indicating a pause portion before a music piece also at the beginning of the recording operation. An audio signal to be recorded is delayed by a predetermined delay time period, to produce a delayed audio signal. Upon starting the recording operation, a muting operation is effected to the delayed audio signal and a resultant signal is recorded on the recording medium during the predetermined muting period after the start of the recording. During this period, a subcode information signal containing the index number signal indicating a number '0' is also recorded on the recording medium.

An audio signal recording apparatus is constructed to record a track number signal which allows a sure detection of a head position of a music piece. An audio signal to be recorded is delayed for the recording by a first predetermined time period. A start time of each music piece is detected by a transition from a silent state to a sound bearing state of the audio signal, and a track number signal is incremented at a timing of a second predetermined time period, which is shorter than the first predetermined time period, after a detection of the start time of a music piece, and the track number signal having been incremented.
