Abstract

PURPOSE:To make it possible to control the tape tension accurately even under the high speed tape running conditions, by utilizing the counter electromotive force generated by the reverse rotation of the reel motor on the supply side at the high speed tape running, and by pulse-driving the reel motor on the supply side. CONSTITUTION:A positive signal SH is supplied to an input terminal 12 on the winding side, a pulse-width modulation signal SV for controlling the tape speed is applied to an input terminal 1, and the reel motor 6A is driven in the forward direction. While the reel motor 6B on the supply side is driven in the same direction as the forward rotation of the reel motor 6A on the winding side; a counter electromotive force is generated, and the rotation suppressing force is generated. To the input terminal 12, since a pulth-width modulation signal ST for controlling the tape tension is applied, the rotation suppressing force generated in the reel motor 6B is controlled, thereby the tape tension is controlled.
