ABSTRACT:
A high-density magneto-optical disk apparatus is provided for removing a cross talk between signals of an adjacent track with respect to a track to be reproduced during reproduction of a signal recorded on a magneto-optical disk. In the case that a track pitch is narrowed for high-density recording in a magneto-optical disk apparatus, a cross talk occurs between a track to be detected and an adjacent track thereto. The magneto-optical disk apparatus uses a phase modulation optical element to form an optical spot having a linear polarizing state in a reproduction track and a circular polarizing state in an adjacent track, on the recording surface of the magneto-optical disk. Accordingly, although a track pitch is considerably reduced compared with the optical spot, a signal interference effect, that is, a cross talk between tracks can be removed to thereby provide a high-density magneto-optical disk.
