发明名称 Magneto-optical recording medium and reproducing method for information recorded on the medium
摘要 A magneto-optical recording medium capable of perfectly masking a mark adjacent to a mark to be reproduced to thereby improve a 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.
