ABSTRACT:
A magneto-optical recording medium having an improved durability or reliability is obtained by providing a protecting layer of an alloy of titanium with one or more of chromium, rhenium and tantalum. This titanium alloy protecting layer has an improved resistance to oxygen, water, chlorine, and acids, etc. and provides an improved resistance to the environment and attacks from the synthetic resin substrate or other layers constituting the medium, such as a dielectric layer and a reflecting layer.
