MAGNETO-OPTICAL RECORDING MEDIUM

摘要

A magneto-optical recording medium has at least a reproducing layer and a recording layer which are magnetically coupled with each other. The reproducing layer permits recorded signals to be read out according to its change in state of magnetization. The reproducing layer has a thickness in a range from 150.ANG. to 1000.ANG.. Additionally, the magneto-optical recording layer has a layer of a goad heat conductor attached thereto. Furthermore, the reproducing layer or the auxiliary reproducing layer is formed of layers of rare earth metal and layers of transition metal which are laminated in alternating fashion.
