Abstract
Disk storage apparatus includes a loading and unloading mechanism for moving a recording disk from an insertion position to a reproduction position within the apparatus. When the disk is in the reproduction position, a locking mechanism is moved out of contact with an actuator which carries a read/write head so that the head can be moved across the surface of the disk by a motor mounted on the actuator. When an eject command is received, the actuator is moved to an inner crash stop and the disk is moved out of the reproduction position causing the locking mechanism to move into mechanical engagement with the actuator. A magnet carried on the locking means is moved adjacent a magnet within the motor so that the mechanical locking engagement is enhanced magnetically.
