ABSTRACT:
A magnetooptical recording medium for information recording and information reproduction includes plural thin films, including at least a reproducing layer and a recording layer, laminated on a substrate. The reproducing layer is composed of a magnetic thin film which assumes a horizontally magnetized state at room temperature but assumes a vertically magnetized state above a predetermined temperature higher than the room temperature. The magnetization in the horizontally magnetized state is free from vertical orientation, including the magnetic wall. The recording layer is composed of a magnetic thin film which assumes a vertically magnetized state at room temperature and above the predetermined temperature.
