ABSTRACT:
A magneto-optical recording medium includes a first magnetic layer of which the magnetic wall moves and which contributes to reproduction, a third magnetic layer in which information is accumulated, and a second magnetic layer disposed between the first and third magnetic layers and having a lower Curie temperature than those of the first and third magnetic layers. The following is satisfied at the lowest temperature Ts whereat the exchange-coupling between the first and third magnetic layers is cut:
