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.

摘要： A magneto-optical recording medium having a recording layer made of a bismuth-substituted garnet and deposited by a sputtering over an amorphous substrate of aluminosilicate or borosilicate glass, the recording medium including a garnet underlayer of either a double-layer or single-layer structure. The formation of an underlayer of a double-layer structure made of garnet reduces the level of noise due to light scattering at crystalline boundaries in the garnet film. The formation of an underlayer of a single-layer structure made of a garnet having a lower crystallization temperature than a YIG film is also effective to noise-level reduction. An underlayer has a surface smoothness corresponding to a roughness of approximately 10 .ANG., which is improved from the surface smoothness of a conventional underlayer comprising a YIG film.
