ABSTRACT:
An optical head applies a laser beam to a region of the magnetooptical disc, and a magnetic head applies a magnetic field to the region of the magnetooptical disc while the laser beam is being applied thereto, thereby to record information in the region. The optical and magnetic heads are interconnected by a link mechanism so that they are movable in unison with each other radially with respect to the magnetooptical disc. An electromagnetic shield is disposed around the magnetic head for blocking magnetic and electric fields parallel to the magnetooptical disc.
