Magneto-optical recording medium having lands and grooves of discontinue regions

摘要

A magneto-optical recording medium has a plane structure in which are alternately arranged a groove having discontinuous regions formed at every 120 &mgr;m, for example, and land having discontinuous regions formed at the same every 120 &mgr;m. The position where the discontinuous region of the groove is formed differs from the position where the discontinuous region of the land is formed. The discontinuous region of the land is provided at a position corresponding to substantially the middle of respective continuous regions of the groove. The discontinuous region of the groove is provided at a position corresponding to substantially the center of the continuous region of the land. The width of the groove and land is approximately 0.4 &mgr;m. Therefore, a synchronizing signal arising from a discontinuous region formed periodically at the groove or land can be output properly even when the width of the groove and land is narrowed.
