发明名称 Rewritable high density magneto-optical disk
摘要 A magneto-optical recording medium capable of performing light-intensity-modulation direct overwrite and having excellent practical characteristics is provided. A magneto-optical recording film is formed by stacking a reproducing layer made of a magnetic material from which a large Kerr rotation angle can be obtained, a memory layer made of a magnetic material having great magnetic anisotropy, an intermediate layer having small magnetic anisotropy and made of TMrich rare earth-transition metal amorphous alloy, a recording layer having a Curie temperature higher than those of the memory layer and the intermediate layer and made of TMrich rare earth-transition metal amorphous alloy, a switching layer made of a magnetic material having a Curie temperature lower than that of the recording layer and an initializing layer made of a magnetic material having a Curie temperature higher than those of the reproducing layer, the memory layer, the intermediate layer, the recording layer and the switching layer.
