A manufacturing method of a domain wall displacement type magneto-optical
recording medium comprises the steps of depositing a magnetic layer on a
substrate to prepare a disc, and irradiating the magnetic layer with a
converged light beam while applying a magnetic field and annealing the
magnetic layer a converged light beam between information tracks. A
domain wall displacement type magneto-optical disc comprises a domain
wall displacement layer in which a domain wall displaces, a memory layer
that holds a recording magnetic domain according to information, a
switching layer that is provided between the domain wall displacement
layer and the memory layer and has a Curie temperature lower than that of
those layers, and a disconnecting area that is provided in the domain
wall displacement layer and disconnects a switching connection between
information tracks, wherein the polarity of a residual magnetization at a
boundary between the information track and the disconnection area is
oriented in a certain direction.
