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. Each of the optical head and the magnetic head is slidably held by guide members so as to be moved in a radial direction of an optical disc. Permanent magnets are mounted on both heads for attracting each other head. Thus, when one of the head moves, the other follows.
