。[Claims for Utility Model Registration] 1 Of the tracks of a magnetic tape on which a video signal and an audio signal modulated by pulse code modulation are recorded in two using the helical scan method, the track on the side where the video signal is recorded is The width of the magnetic tape is divided into a plurality of sections along the running direction of the magnetic tape, and an audio signal modulated by pulse code modulation is recorded and played back on each divided track using a plurality of recording/playback heads. In the magnetic recording and reproducing apparatus, fixed erasing means is provided in front of the recording/reproducing head on the magnetic tape running path in the magnetic tape running direction for erasing the audio signals recorded on each divided track in each of the divided areas. A magnetic recording/reproducing device characterized by: 2. The fixed erasing means is made of a prismatic body and has a part on its magnetic tape running surface corresponding to each of the partitioned areas,
2. A magnetic recording and reproducing apparatus according to claim 1, wherein each erase head is provided with a width equivalent to the width of the section.
