In a rotary head type magnetic tape video recording-reproducing device of the type in which a magnetic tape from a supply reel is wrapped around a rotary drum carrying magnetic heads along the path of revolution thereof at an angle other than 0.degree. relative to the axis of rotation of said rotary drum, and is taken up by a take-up reel for recording or reproducing, when a stop button is depressed or the power supply to a take-up reel driving motor is interrupted, the motor is stopped and then immediately reversed in direction for a predetermined time, thereby loosening the tension of the magnetic tape. This arrangement prevents the adhesion of the magnetic tape to the surfaces of the magnetic tape passages, especially of the rotary drum, due to the moisture or the condensation of vapor so that the smooth re-starting of the magnetic tape may be ensured.
A rotary head type magnetic tape video recording-reproducing device of the type wherein a magnetic tape is transported to and from and is wrapped at least one turn around a rotary member carrying at least one rotary magnetic head along a path of revolution thereof at an angle other than 0.degree. relative to the axis of rotation of said rotary member for sequentially recording information upon said magnetic tape or reproducing information therefrom during transport of the tape, and wherein one end of said magnetic tape is wrapped around a supply reel and the other end thereof wrapped around a take-up reel, means including a power supply for selectively driving one of said reels, the improvement wherein means are provided responsive to the interruption of said power supply for reversing the direction of said selected driven reel through a predetermined angle.
