置。 When recording one subject on a magnetic disk,
In a device that can play back a video signal in which one frame is recorded on two tracks by selecting frame playback or field playback,
An operation switch is provided that can forcibly switch to a field playback mode when reproducing the frame-recorded contents, and an operation pulse signal is output each time the operation switch is operated. A magnetic disk playback device characterized in that a headstitching pulse synchronized with a signal for detecting the rotational phase of a disk rotation motor is cyclically and sequentially converted into a switching pulse for first and second field playback every time the magnetic disk rotates. .
