<p>A magneto-optical recording medium is constructed by a reproduction layer (11) which assumes an in-plane magnetization state at room temperature and becomes a perpendicular magnetization film at temperatures between room temperature and a Curie temperature, a recording layer (13) for storing information, and an intermediate layer (12) which is arranged between the reproduction layer and the recording layer and in which a Curie temperature is lower than those of the reproduction layer and the recording layer and which is iron group element sub-lattice magnetization dominant. Each of the layers is constructed by a rare earth-iron group element amorphous alloy and the intermediate layer is made of a material, as a main component, which satisfies ÄGdx(Fe100-y Coy)100-xÜ (8 ≤ x ≤ 15, 0 ≤ y ≤ 50). The reproduction layer has a compensation temperature between room temperature and the Curie temperature. <IMAGE> <IMAGE> <IMAGE></p> |
