Abstract
A magneto-optical disk device for receiving a magneto-optical disk housed in a cassette and for driving the magneto-optical disk by a disk drive motor to read/write the disk is disclosed. The device includes a movable cassette carrier having a top plate for receiving the cassette therein, a read/write head located under the cassette carrier, a magnetic field coil slidably mounted on the top plate above the read/write head to move in a direction parallel to the movement of the read/write head, a pole extending substantially perpendicular from the read/write head at a position offset from the cassette carrier, and an arm having one end slidably mounted on the pole and other end fixedly connected to the magnetic field coil. The arm is mounted to slide along the pole to move the magnetic field coil along a direction substantially perpendicular to the disk.
