装置。 A magnetic field generating coil attached to move in the radial direction of the disk integrally with the optical head can be controlled by an electromagnetic drive means in a direction perpendicular to the disk surface, and the electromagnetic drive means can be moved in a direction perpendicular to the disk surface. The distance between the disk surface and the magnetic field generating coil is maintained constant by being driven by the output of a non-contact type position sensor that detects the displacement of a cantilever energized to make contact with the disk surface. Features of magneto-optical disk drive device.
