In a magneto-optical recording medium, a first magnetic layer for participating in reproduction of information is laminated on a substrate. A second magnetic layer for storing information is laminated on the first magnetic layer. A third magnetic layer having a Curie temperature lower than those of the first and second magnetic layers is disposed between the first magnetic layer and the second magnetic layer. A magnetization of a region of the first magnetic layer adjacent to a region of the third magnetic layer the temperature of which is above the Curie temperature of the third magnetic layer is aligned with the direction of magnetization of a region around the region of the first magnetic layer.
