ABSTRACT:
A magneto-optical recording medium in the form of a thin amorphous alloy film having the following composition of Gd-Nd-M-Fe (M: at least one of Dy and Ho), has an axis of easy magnetization in a direction perpendicular to the surface of the film. The M density is at least sufficient to keep the Curie point below 300.degree. C.
