摘要：
A Magneto-Optical disk having a transparent substrate, a Magneto-Optical film formed on the transparent substrate and a high corrosion-resistant film laminated on the Magneto-Optical film. The Magneto-Optical film is made of a perpendicular magnetic anisotropy material, the corrosion-resistant film is made of a metal or metal alloy. A foundation protecting layer may be formed on the transparent substrate with the Magneto-Optical film and the corrosion resistant film formed thereon. The Magneto-Optical film may be a plurality of films laminated alternately with a plurality of corrosion-resistant films.
