ABSTRACT OF THE DISCLOSURE 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° 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 pre- determined 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 restarting of the magnetic tape may be ensured.
