Title: Magneto-optical recording medium and method and equipment for manufacturing the same
Inventor: YOSHIBE SATOMI
IPC: G11B11/10
Filed: 1994-07-22
Abstract: PURPOSE:To enable execution of overwrite by aligning directions of magnetization of a medium uniform into one. CONSTITUTION:A medium wherein a direction of magnetization of a recording layer W is made a prescribed one without changing the direction of magnetization of a memory layer M at room temperature is prepared by laminating the layers M and W which are constructed with magnetic thin films being magnetizable vertically and are put in exchange coupling with each other. The direction of magnetization of the layer W is aligned by impressing a magnetic field being larger than the coercive force of the layer M and the direction of magnetization of the layer M is aligned by applying a laser beam, at room temperature. Erasure of a record is conducted by applying the laser beam to a land part. Between lands, a groove prepared by forming a film of the magneto-optical recording medium is provided. Ordinary erasure is not conducted in this groove and, accordingly, the direction of magnetization can not be made to match with the layer W by the application of the beam. In other words, the direction of magnetization of the groove is left as it is initially, even when overwrite is repeated on the lands.
