发明名称 Magneto-optical recording medium with first and second magnetic layers with almost equal Curie temperatures
摘要 A magneto-optical recording medium includes at least three magnetic layers of a first magnetic layer, a second magnetic layer and a third magnetic layer, in which a recording mark recorded in the third magnetic layer by irradiation of a light beam is transferred through the second magnetic layer formed above the third magnetic layer to the first magnetic layer formed above the second magnetic layer for reproduction, wherein the first magnetic layer is provided with a high temperature mask having no spontaneous magnetization in a region where its temperature becomes a predetermined temperature or higher.
