发明名称 MAGNETO-OPTICAL RECORDING MEDIUM
摘要 A magneto-optical recording medium is provided which has high magneto-optic effect even under a short-wavelength light, high anisotropy in the direction perpendicular to the film surface, and permits high-density recording, the medium having a first magnetic layer laminated onto a second magnetic layer, the first magnetic layer being a rare-earth-transition-metal amorphous film with mainly a light rare-earth element as rare-earth element, the light rare-earth element being at least one element selected from an element group consisting of Nd and Pr, and the second magnetic layer being a rare-earth-transition-metal amorphous film with at least one element selected from an element group consisting of Tb and Dy as rare-earth element.
