Abstract
In a video tape recorder and/or reproducer, the power of a capstan motor for driving a magnetic tape is utilized as the power for driving reels in a cassette. In order to facilitate controlling the tension of the magnetic tape at the time of a change in the travelling direction of the tape in an intermittent tape travel mode, it is possible to drive a feed-side reel without turning OFF a back tension servo mechanism which applies back tension to the feed-side reel. In this state, the change in the travelling direction of the magnetic tape is performed by only controlling the direction of rotation of the capstan motor.
