Abstract

PURPOSE:To prevent variation in tape running speed at a head position by setting the rotational frequency of a slip disk in such a way that tape speed variation due to the elongation of a tape and that due to variation in the load torque of a capstan cancel each other. CONSTITUTION:When a flywheel 2 is rotated as shown by an arrow A by a driving motor 10, a tape 8 runs forward as shown by an arrow B through a capstan 1 and a pinch roller 3 and the rotation of the capstan 1 is transmitted to a slip disk 6 through an intermediate pulley 7 and an idler 11, winding the tape 8 around a reel 5. To drive the tape 8 in the opposite direction, the idler 11 is changed over to the other slip disk 6'. Further, the rotational frequency of the slip disk 6 is set properly in such a way that variation in tape running speed at the position of a head 4 due to variation in the tension of the tape 8 is eliminated.
