Claims

[Scope of utility model registration request]

A magnetic head mounted on a rotating cylinder records and reproduces signals on a magnetic tape, and a fixed head placed on the magnetic tape winding side of the cylinder synchronizes the signal recording area of the same magnetic head with a control track at a different position. In a video tape recorder that records and reproduces a synchronization signal synchronized with the rotation of a cylinder and a control code representing a signal recording position on the magnetic tape superimposed on the same synchronization signal, a skip key provided on the main body is provided when the video tape recorder is in a playback mode. When the control unit detects the rising edge of the control signal recorded on the control track by the fixed head in the playback state, it outputs a synchronization pulse and switches the fixed head to the recording state, When you update the control code recorded in the ``skip code'' to a skip code, and when the same skip code is confirmed in the control signal read when the same skip key is not operated, the video tape recorder is switched to fast-forward mode, and the control signal read out in the same fast-forward mode is updated. A video tape recorder characterized in that it returns to playback mode when the same skip code is confirmed.
