ABSTRACT:
A magneto-optical record/reproduce apparatus utilizes a magneto-optical record medium having a surface on which a record area and a non-record area are defined, the non-record area having a lower friction than that of the record area. The apparatus includes a record/read head disposed in the vicinity of the surface of the magneto-optical record medium, the record/read head being moved away from the magneto-optical record medium during a running state of the magneto-optical record medium for recording or reading information, the record/read head being in contact with the magneto-optical record medium during a stop state of the magneto-optical record medium after terminating the recording or reading of the information, a termination detect section for detecting a termination of the recording/reading of the information related to the magneto-optical record medium, and for outputting a termination detect signal, and a move device for moving the record/read head to a position facing the non-record area based on the termination detect signal from the termination detect section.
