Filed: 1992-06-11
Abstract: PURPOSE:To prevent the slip of a disk carrier and to prevent the deformation and the destruction of a recording face by installing an electromagnetic solenoid which helps the magnetic field of a permanent magnet for disk attraction. CONSTITUTION:In a loading operation, a disk device detects that a carrier has been inserted, supplies an electric current to a solenoid 7 and strengthens the attractive force of a permanent magnet 5. A motor 9 is driven. When a hub 3 is turned steadily, the electric current of the solenoid 7 is cut off. Consequently, the disk carrier is not slipped on the face of the hub 3. In an unloading operation, an electric current is first supplied to the solenoid. After a prescribed time, the motor 9 is decelerated, and the rotation of the hub 3 is stopped. During this time, since the attractive force of a central metal part is strengthened, the carrier is not slipped on the face of the hub 3. When the hub is stopped, the action of the solenoid is stopped, a loading mechanism is actuated, the carrier is detached from the hub and a cartridge case is discharged.
