Abstract
A recording/reproducing apparatus, specifically, a video tape recorder, in which time losses in performing connection recording due to transitions through a winding and/or reproducing mode when changing from the recording pause mode or the like to the recording mode are substantially eliminated. A capstan motor is employed with which the time required for the speed of the tape driven by the motor to reach zero from the normal operating speed is smaller than a period corresponding to a single frame of the recording video signal. The timing of the start of deceleration of the capstan motor is controlled such that a level transition of a changeover signal for the recording head occurs in a period of deceleration of the capstan motor when the operating mode is changed from the recording mode to the recording pause mode. The recording current supplied to the recording head is cut off at the same time as the level transition of the recording head changeover signal.
