MAGNETO-OPTICAL RECORDING MEDIUM |
摘要 |
A magneto-optical recording medium is disclosed in which magnetic layer has a multi-layer structure consisting of an artificial lattice film constituted by a Co layer and a Pt layer and/or a Pd layer stacked together and a rare earth - transition metal layer. High coercivity may be achieved by the rare earth - transition metal film whilst a satisfactory Kerr rotation angle in the short wavelength range may be assured by the artificial lattice film. The magneto-optical recording medium may cope with the next-generation high density recording employing a short wavelength laser. <IMAGE> |
