PURPOSE:To miniaturize a device with simplified structure by constituting the titled device so that a magnetic head is returned to a landing zone by using inertial force of a recording disk and a synchronizing motor. CONSTITUTION:Disconnection of a power source circuit 12 turns relays K1 15 and K2 21 to off, and disconnects a contacting point 22 and thus an armature coil 23 of a synchronizing motor 4 is separated from a synchronizing motor drive circuit 5. The motor 4 and a recording disk 1 are rotated by inertial force. The output generated by the motor 4 is rectified by diodes 24-26 to become DC, and a contacting point 16 is disconnected and an actuator drive circuit 11 is separated. Thus the rectifying output of the diodes 24-26 flows through a movable coil 8 of actuator to return a magnetic head 6 to a landing zone 2. |
