摘要：
A method of making a magneto-optical recording medium comprises the step of forming a magneto-optical recording layer on a substrate by simultaneously carrying out direct current sputtering and radio-frequency sputtering. Alternatively, a magneto-optical recording layer composed of thin rare earth metal layers and thin transition metal layers overlaid alternately on a substrate is formed by carrying out radio-frequency sputtering by use of a target formed of a rare earth metal material and direct current sputtering by use of a target formed of a transition metal material.
