Abstract

PURPOSE:To optimize the control of tape tension, by compensating the response delay due to loop gain reduction, through an overshoot caused to the tension reference when a tape speed is changed from a high to a low value. CONSTITUTION:Switches 15 and 16 are selectively switched and a reference voltage Vs1 is set in response to tape running modes FF, STILL and REW. At the FF mode, a capstan speed detecting voltage Vcap is changed according to the speed and the Vs1 is changed accordingly. The Vs1 is differentiated at a compensation circuit 20 to obtain a Vs2 with overshoot. Further, the undershoot produced in this case is rejected at a clamp circuit 21. The Vs2 and a VT1 from a detector 24 are compared to obtain a Vc1 and Vc2 is obtained, which controls a motor 8.
