ABSTRACT The magnetooptical recording media according to the present invention comprise a substrate, a protective film, a magnetooptical recording film, an aluminum alloy film and a nickel alloy film. Such magnetooptical recording media have excellent mechanical characteristics such as little warpage formation, little dependence of recording power on linear velocity, a broad margin of recording power, excellent erase-read-write cyclability and excellent oxidation resistance and recording sensitivity. |
