ABSTRACT:
Disclosed is magnetoptical disc apparatus for recording information in magnetoptical recording medium using a floating type magnetic head. The apparatus includes a floating type magnetic head for applying a modulated magnetic field to the medium, a leaf spring for supporting the magnetic head floatably above the medium, a retreating mechanism for moving the magnetic head from a position at which the magnetic head can contact the medium and a limiting device for limiting a deflection of the leaf spring when the retreating mechanism moves the magnetic head from the above-mentioned position. The driving stroke needed for moving the magnetic head can be reduced, and as a result, the retreating mechanism can be made small in size.
