摘要：
A magneto-optical recording medium is composed of a base which has a property that a light can be transmitted therethrough, a readout layer formed on the base, which has in-plane magnetization at room temperature, whereas, a transition occurs from in-plane magnetization to perpendicular magnetization as the temperature thereof is raised and a recording layer formed on the readout layer for recording information magneto-optically.
An intermediate layer made of non-magnetic film is formed between the readout and recording layers.
An intermediate layer made of non-magnetic film is formed between the readout and recording layers.
