Abstract

MPU(8)는 헤드의 이동속도가 목표속도에 도달한 시점에서 선정된 감속개시점까지 이르는 동안 헤드(1)의 이동속도가 목표속도를 포함하는 선정된 범위내에 있는지의 여부를 판정한다. 판정한 결과, 선정된 범위내에 있는 경우에는 음성 코일 모터(2)로 보내는 전류를 모터 작동기(11)에 의해 차단하고 선정된 범위내에 있지 않는 경우에는 모터 작동기(11)에 의해 음성 코일 모터(2)로 전류를 공급한다.The MPU 8 determines whether or not the moving speed of the head 1 is within a predetermined range including the target speed while the head moving speed reaches the selected deceleration start point from the time when the head speed reaches the target speed. As a result of the determination, the current sent to the voice coil motor 2 is interrupted by the motor actuator 11 when it is within the selected range, and the voice coil motor 2 is prevented by the motor actuator 11 when it is not within the selected range. Supply current.
