摘要： A magneto-optical disk drive that prevents the track shift signal from overlapping the MO signal, even when the optical head projects a divergent spherical wave onto the beam splitter. This objective is realized by a magneto-optical disk drive that uses an optical head which emits a divergent spherical wave onto a beam splitter surface of a beam splitter. Since the tracking error signal, which is overlapped by the MO signal of the MO detection unit, is synchronous with the tracking signal, a correction circuit is used to overlap the MO signal with the tracking error signal and to eliminate errors caused when the track shift signal overlaps the MO signal.
