ABSTRACT:
Video tape recording apparatus with means for editing the recorded material without significant sudden change in current to the capstan motor. During recording of the added or replacement material the capstan motor is controlled by comparing the phase of a fixed high frequency signal with a signal generated synchronously with rotation of the capstan motor. The fixed frequency signal can be generated by a stable oscillator or by using submultiples of fixed-frequency components of the video signal.
