PURPOSE:To prevent the generation of moire by recording and reproducing an audio signal by an exclusive rotary audio head. CONSTITUTION:In forming a track T2 on a tape 6, after an audio signal is recorded by an audio head 3, a video signal is recorded on the same track T2 by being superimposed on the audio signal by a video head 11. In forming the track T4, the signal is recorded similarly. The video signal is recorded with azimuth on adjacent tracks T1-T4- at each field by video heads 11, 12, the audio signal for one frame's share is recorded with azimuth on tracks T2, T4 at each other track by the audio head 3 while taking video signal tracks T1, T3- as guard bands with time compression on one track. |
