Magneto-optical disc apparatus with means to change the angle and distance between a magnetic field generating source and a magneto-optical disc

摘要

The present invention is directed to a magneto-optical disc apparatus which includes a magnetic field generating source (12). The magnetic field generating source (12) is disposed so as to become freely rotatable with respect to a magneto-optical disc (1) and a spacing between it and the magneto-optical disc (1) can be changed. Plural kinds of magneto-optical discs can be recorded and reproduced with a compatibility by the common magnetic field generating source (12).
