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 .
