A domain wall displacement type magneto-optical recording medium is provided that can perform stable domain wall movement and prevent cross-write while adopting the land/groove recording to attain a narrow track pitch. The magneto-optical recording medium includes a magnetic layer of a stack structure formed of a domain wall displacement type reproducing layer, a switching layer and a record holding layer, wherein both a land and a groove are used as a recording/reproducing track, and wherein a side wall portion located between the land and the groove is irradiated with a light beam to be annealed.
