Abstract
A magneto-optical recording medium has a domain wall displacement layer, a recording layer for accumulating information and a switching layer arranged between said domain wall displacement layer and said recording layer and having a Curie temperature lower than those of the latter two layers. The domain wall displacement layer, the switching layer and the recording layer are coupled by exchange coupling at temperature not higher than the Curie temperature of the switching layer. The saturation magnetization of the domain wall displacement layer and the recording layer are in opposite directions to each other when the layers are coupled by exchange coupling at a temperature close to the Curie temperature of the switching layer.
