装置。[Claims for Utility Model Registration] On the outer periphery of the rotating drum, in order in the direction of rotation,
A high-speed video tape comprising an erasing head for erasing video and audio signals recorded on a video tape, an audio recording/playing head for recording and playing back the audio signals, and a video recording/playback head for recording and playing the video signals. In the recorder, a video playback head for playing back the video signal is provided before the erasing head, and a memory is provided in which the video signal played back by the video playback head is written. The video recording and playback head is provided with a video signal output circuit that outputs the position traced by the video playback head on the tape with a delay corresponding to the tape movement time until the video recording and playback head traces the position,
A high-fidelity video tape recorder characterized in that, after the audio on the tape is rewritten by the audio recording/playback head, the video signal written in the memory is re-recorded by the video recording/playback head. After-recording equipment.
