摘要： An aspect of the present invention provides a master medium for perpendicular magnetic transfer, comprising: a disk-like substrate on a surface of which a plurality of protruding magnetic-layer patterns corresponding to information to be transferred to a magnetic recording medium targeted for transfer are formed. In the master medium for perpendicular magnetic transfer, a ratio of a circumferential width L of the protruding magnetic-layer patterns to a circumferential gap S between the protruding magnetic-layer patterns is L/S

摘要： A magneto-optical recording medium capable of perfectly masking a mark adjacent to a mark to be reproduced thereby improvng reproduction output. The magneto-optical recording medium includes a transparent substrate, a magnetic reproducing layer laminated on the transparent substrate, a nonmagnetic intermediate layer laminated on the magnetic reproducing layer, and a magnetic recording layer laminated on the nonmagnetic intermediate layer. The reproducing layer has an easy direction of magnetization in a plane at room temperature, and has an easy direction of magnetization perpendicular to a film surface at a given temperature or higher. The nonmagnetic intermediate layer is thin enough to allow magnetostatic bond between the recording layer and the reproducing layer at the given temperature or higher. Instead of the nonmagnetic intermediate layer, a magnetic intermediate layer having an easy direction of magnetization in a plane from room temperature to its Curie temperature may be interposed between the reproducing layer and the recording layer.
