A magnetic field generating section for recording is supported by the cartridge holder and one end thereof is supported by the other end of the load lever which can be engaged with the stopper, and the magnetic field generating section is set at the recording/reproducing position by a spring. In the magneto-optical disk device which is biased in a direction approaching the magneto-optical disk, one end of the load lever that can engage with the stopper is provided with the cartridge holder near the insertion/removal position of the magneto-optical disk. A magneto-optical disk device, characterized in that a cam-shaped cam portion is formed to move the load lever in the opposite direction so as to offset the movement of the magnetic field generating portion accompanying the movement of the magneto-optical disk device.

Claims

[Scope of utility model registration request]

A slide plate with a protruding stopper supports the cartridge holder in a movable manner so that the magneto-optical disk can be inserted into and removed from the disk and the recording/reproducing position, and the holding force of the magnetic film of the magneto-optical disk is reduced. A magnetic field generating section is supported by the cartridge holder and one end thereof is supported by the other end of the load lever which can be engaged with the stopper, and the magnetic field generating section is supported by a spring at the recording/reproducing position. In a magneto-optical disk device that is biased in a direction approaching the magneto-optical disk, one end of the load lever that can engage with the stopper is attached to the cartridge holder in the vicinity of the insertion/removal position of the magneto-optical disk. A magneto-optical disk device, characterized in that a cam-shaped cam portion is formed to move the load lever in the opposite direction so as to offset the movement of the magnetic field generating portion accompanying the movement.
