Magnet-optical disc drive device.

摘要

A magnet-optical disc drive device comprises a disc driving mechanism (9) which includes a drive shaft (14) powered by an electric motor (13). A magnet-optical disc (D) is detachably connected to the drive shaft. A magnetic field modulation head (H) is positioned at one side of the disc, and an optical unit (30) is positioned at the other side of the disc. A moving mechanism (10) 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 (H) 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. <IMAGE>
