Magneto optical recording medium

摘要

A magneto optical recording medium comprising the following elements has been developed: a substrate; an interference layer of tantalum oxide having 500 to 1,200 ANGSTROM in thickness and formed on said substrate; a recording layer formed on said interference layer; a heat insulating layer of silicon nitride, silicon oxide or a mixture thereof having 200 to 500 ANGSTROM in thickness and formed on said recording layer; and a reflective layer of Al or an Al-based alloy having 400 to 1,200 ANGSTROM in thickness and formed on said heat insulating layer.
