A magneto-optical medium of a domain wall displacement type is provided which does not cause inward leakage of signals caused by domain wall displacement from the rear of a reproducing light spot. The magneto-optical medium comprises a domain wall displacement layer, a switching layer, and a memory layer. The switching layer has a boundary temperature higher than room temperature for transformation from a state of a perpendicular magnetization film to a state of an in-plane magnetization film.
