Abstract
PURPOSE:To minimize an error of a static position of the motor remarkably by increasing a proportional gain of the stoppage control circuit to a high gain just after modes transfer to a stoppage controlling mode from a speed controlling mode and changing over the proportional gain to a low gain after a fixed time passes. CONSTITUTION:In the speed controlling mode, an analog switch ASW1 is at off and an ASW2 is at on, and speed control signals S11 from a speed control circuit are inputted to an operational amplifier OP-AMP of a head amplifier 3. When the modes are changed over to the stoppage controlling mode, changeover control signals S92 from a processor change to a level L from a level H, and the switch ASW2 is at off and the ASW1 is at on while changeover control signals S91 are given at the level L, thus keeping a switch ASW3 under an on condition, then increasing the proportional gain to a comparatively large value. Since the signals S91 change to the level H after a fixed time passes after a point of time when the modes transfer to the stoppage controlling mode, the switch ASW3 is at off, and the proportional gain is minimized more than that just after transfer.
