ABSTRACT:
A magneto-optical disk drive system is provided with a housing and a disk cartridge for housing a magneto-optical disk therein. The disk cartridge is insertable into the housing, an optical head is disposed in the housing for movement in a first radial direction of the magneto-optical disk on one side thereof. A magnetic head is disposed in the housing for movement in a second radial direction of the magneto-optical disk on an opposite side thereof, and a position sensor is coupled to the optical and magnetic heads, for detecting the relative position of the optical and magnetic heads. A first position adjuster disposed in the housing for aligning the first and second radial directions with each other, second position adjuster disposed in the housing for positionally aligning the optical head and the magnetic head with each other across the first and second radial directions, and third position adjuster is disposed in the housing for positionally adjusting the position sensor with respect to the optical head and the magnetic head along the first and second radial directions.
