Process for producing a magneto-optical recording medium

摘要

The invention relates to a process for producing a magneto-optical recording medium by forming a magneto-optical recording layer on a substrate by simultaneously carrying out a direct-current sputtering and a radio-frequency sputtering. Alternatively, a magneto-optical recording layer comprising alternately superposed thin rare earth-metal layers and thin transition-metal layers is formed on a substrate by carrying out a radio-frequency sputtering using a target of a rare earth-metal material and a direct-current sputtering using a target of a transition-metal material.
