Abstract
A PCM (pulse code modulated) audio signal recording and/or reproducing apparatus, operates with plural scanning periods, in which a rotary head scans obliquely the longitudinal direction of a tape, and which scanning periods are separated into a plurality of segment periods. PCM audio signals are recorded on one or more channels of a plurality of track channels, formed by the alignment of respective segment tracks which are scanned by the rotary head during the corresponding segment periods of each scanning period, and an identifying signal, indicative of the fact that the PCM audio signals is already recorded, is superimposed upon the PCM audio signal and recorded together therewith on the track channels, whereby it becomes possible to easily identify whether or not the PCM audio signal is recorded on the of track channels.
