ABSTRACT:
A device is provided for selecting a magnetic head to be operated together with an optical head to record or reproduce a signal on a magneto-optical disc. The device includes a first magnetic head and a second magnetic head, each having different capabilities. The first and second magnetic heads are arranged along a radial direction with respect to a magneto-optical disc. The device is capable of determining the type of magneto-optical disc being used, and upon such determination, controls the position of a carriage to position either the first or second magnetic head to face the optical head.
