Claims

[Scope of utility model registration request]

A video signal playback device that performs still playback or intermittent tape-feeding slow-motion playback by controlling a tape stop position in synchronization with a playback signal of a control signal recorded on a tape, which includes a main and auxiliary control head, and The position of the auxiliary control head relative to the main control head such that the control signal can be reproduced by the auxiliary control head at a position substantially earlier than the recording position of the control signal recorded by the main control head relative to the video signal track. A video signal reproducing device comprising:
