の頭出し機構。[Claim for Utility Model Registration] An erasing head that comes into contact with a tape running at a constant speed in a loading state completes a cue signal, detects the cue signal from the recorded tape, and unloads the tape in order to play back a desired position on the tape. A full-width erase head is used in a video tape recorder that detects a cue signal at the playback head that comes into contact with a tape running at high speed in a loading state, stops the tape running, then enters a loading state and starts playback. a narrow cueing signal reproducing means that is integrated into the tape and comes into contact only with the video signal recording area of the tape running after loading; and detecting a cueing signal derived from the cueing signal reproducing means and starting the playback operation. A cueing mechanism for a video tape recorder, characterized in that a mode switching circuit is provided.
