Abstract

PURPOSE:To obtain a medium which has excellent initial characteristics and long-term reliability and is easy to form by using a specific alloy for an amorphous magneto-optical recording layer. CONSTITUTION:The magneto-optical recording layer 3 consisting of the alloy, which is expressed by the formula (LRxHR1-x)yA1-y-zBz and in which 0<x<0.5, 0.1<y<0.5, 0<z<0.01 and LR is >=1 kinds among Y, La, Ce, Pr, Nd, and Sm, HR is >=1 kinds among Gd, Tb, Dy, A is >=1 kinds among Fe, Co, Ni and B is >=1 kinds among Mn, Tc, Re, Cu, Zn, Cd, is used for the magneto-optical recording medium with which executes recording, reproducing and erasing is executed by projecting light to the amorphous magneto-optical recording layer 3 the direction of which has the direction of magnetization perpendicular to the film plane and takes two values of either upward or downward. The magneto-optical medium which has not only the excellent initial characteristics but also the excellent reliability and relieves the limitation on sputtering conditions is thereby obtd.
