Claims

[Scope of utility model registration request]

A magnetic head is mounted on one end, a moving coil of a drive motor is mounted on the other end, and a lock arm is provided in the middle part of the actuator, which rotates around the middle part as a fulcrum, and driving power is supplied to the moving coil of this actuator. a capacitor that supplies the magnetic head position return power to the moving coil when the drive is stopped; and a relay that conductively connects only the drive power source to the moving coil when the drive is stopped, and conductively connects the capacitor to the moving coil when the drive is stopped. , a position detector that detects the position of the magnetic head, a charger that charges an electric charge according to the output of the position detector, and a ratchet mechanism that stops a lock arm provided on the actuator to limit movement of the actuator. , and a solenoid for releasing the stoppage of the ratchet mechanism.
