Magnet-optical disc drive device with sure disc placement

摘要

A magnet-optical disk drive device comprises a disc driving mechanism which includes a drive shaft powered by an electric motor. A magnet-optical disc is detachably connected to the drive shaft. A magnetic field modulation head is positioned at one side of the disc, and an optical unit is positioned at the other side of the disc. A moving mechanism is employed for moving both the magnetic field modulation head and the optical unit in a radial direction of the disc. The magnetic field modulation head is of a floating type wherein a head proper is forced to float above the surface of the disc due to the force of an air flow which is produced when the disc is rotated.
