Provided is a magneto-optical recording medium capable of accurately
reproducing a signal of a recording density exceeding a resolution of an
optical system without making a constitution thereof complicated. The
magnetic domain wall displacement type magneto-optical recording medium,
comprises: a magnetic domain wall displacement layer in which a magnetic
domain wall moves to contribute to information reproduction; a memory
layer holding a recorded magnetic domain corresponding to the
information; and a switching layer which is arranged between the magnetic
domain wall displacement layer and the memory layer and has a Curie
temperature lower than Curie temperatures of the magnetic domain wall
displacement layer and the memory layer. In the recording medium, the
magnetic domain wall displacement layer is constituted of two or more
magnetized films, and a magnitude of a net magnetization of the magnetic
domain wall displacement layer in a temperature range from the Curie
temperature of the switching layer to the Curie temperature of the
magnetic domain wall displacement layer is substantially zero.
