ABSTRACT:
A magneto-optical recording medium, comprising a substrate, a magneto-optical recording layer on the substrate, a transparent thermally-insulating layer of one selected from the group consisting of tantalum oxynitride and tantalum oxide on the magneto-optical recording layer, and a metal reflecting layer on the transparent thermally-insulating layer, the metal reflecting layer having a thermal conduction represented by a product of a thermal conductivity multiplied by a layer thickness of not less than 1.3.times.10.sup.-6 WK.sup.-1. Heat dispersion is improved while maintaining a high recording sensitivity.
