摘要:
A magneto-optical recording medium is composed of first through fourth magnetic layers laminated in this order in such a way that an exchange coupling exists between any adjacent layers of the first through fourth magnetic layers so that a magnetization direction can be copied, wherein the first magnetic layer is a memory layer, the second magnetic layer is a writing layer, the third magnetic layer is a switching layer, and the fourth magnetic layer is an initializing layer. Further, respective Curie temperatures Tci satisfy an inequation Tc.sub.3
