記録回路が制御されるビデオ・テープ・レコーダー。A recording circuit for obtaining a video signal processed for recording and a frequency-modulated audio signal to be applied to a rotating magnetic head and recorded on a track inclined with respect to the running direction of the magnetic tape, and a recording operation based on the recording circuit. and a control circuit that can obtain a control signal that becomes a negative state at a time when the relative speed of the rotating magnetic head and the magnetic tape reaches a specified speed or is expected to reach a specified speed, The frequency-modulated audio signal is not applied to the rotating magnetic head until the control signal is given to the recording circuit and the control signal goes into the - state, and the control signal goes into the - state. A video tape recorder in which the recording circuit is controlled so that the frequency-modulated audio signal is applied to the rotating magnetic head from a point in time when the frequency-modulated audio signal is applied to the rotating magnetic head.
