Abstract
PURPOSE: To feed a tape to the objective point exactly without making the servo- system step out, by driving the motor by the voltage according to the moving amount from the running point to the objective point, of the recording medium at that time point, in case when reversal of the motor has been detected at the decelerating time of the motor.
CONSTITUTION: When the decelerating control is bein executed, if the motor 1 is reversed, a rotary direction detecting signal becomes a high level from a low level, and it is provided to the AND circuit 14. Moreover, when a pluse signal has been provided, a high level output is obtained from the circuit 14, as a result, FF15 is set, and its output becomes a high level. Accordingly, the AND circuit 16 is closed, a gate signal which has been provided to the AND circuit 7 is cut off, and the circuit 7 is closed. At the same time, an output of FF15 opens the circuit 8 through the OR gate 18. As a result, the output voltage of the D/A converter 5 is applied to the motor 1, and the stationary control is executed. In this way, a tape can be exactly attained to the objective point without making the servo-system step out.
