Magneto-optical recording medium exclusively for reproduction, method of manufacturing the same and method of reproducing the medium

摘要

A magneto-optical recording medium in which a magnetic wall is displaced to thereby enlarge a magnetic domain so as to reproduce a micro magnetic domain indicative of information is effected, includes a non-magnetic substrate, a magnetic layer laminated on the substrate, and a projection-recess portion indicative of information formed on the surface of the substrate. The direction of magnetization of the magnetic layer on the projection-recess portion and the direction of magnetization of the magnetic layer on the other region than the projection-recess portion are oriented oppositely to each other.
