ABSTRACT:
A rotary head type magnetic recording/playback apparatus for recording a video signal and an audio signal on multiple helical tracks formed on a magnetic tape and reproducing the video signal and audio signal therefrom. The apparatus includes a recording section for treating the helical tracks as multiple track groups each including N helical tracks, recording only a video signal on (N-K) helical tracks in each track group used as video-only tracks, and recording a video signal and an audio signal in a mixed manner on K helical tracks used as video/audio mixed tracks, and a reproducing section for reproducing the video signal and audio signal from the helical tracks in each of the track groups.
