ＣＭ記録再生装置。[Claims for Utility Model Registration] A helical device comprising a plurality of rotating magnetic heads, which divides a track of a magnetic tape into a plurality of parts in the width direction of the magnetic tape, and records or reproduces a pulse code modulated signal on each divided track. In a scanning type multi-track PCM recording and reproducing apparatus, at least one of the plurality of divided tracks is used as an index dedicated to recording and reproducing index data indicating the contents of data recorded on other divided tracks. one end of the magnetic tape in the width direction is used as a cueing signal track exclusively for recording and reproducing cueing signals along the longitudinal direction of the magnetic tape, and the index data is pulse code modulated. A dedicated PCM recording and reproducing processing circuit is provided for performing predetermined processing for recording or reproducing on the index track by the rotating magnetic head, and a PCM recording/reproducing processing circuit is provided for recording or reproducing the cue signal on the cue signal track. A multi-track P characterized in that it is provided with a cueing signal processing means comprising a first fixed magnetic head for reproducing and a second fixed magnetic head for erasing a recorded cueing signal.
CM recording and playback device.
