ABSTRACT:
A read-write head of a magneto-optical disc player has an optical head having an optical pickup, and a magnetic head having an electromagnet. The optical head and the magnetic head are each slidably held by guide members so as to be moved in a radial direction of an optical disc. A motor is mounted on each head for moving the head along the guide member. A relative position between both heads at a position where both heads oppose each other is detected, and both heads are moved along the guide members, maintaining the relative position.
