摘要:
A magneto optical disc, is provided with: a record layer to which information is recorded in a perpendicular magnetization condition; a switch layer, which perpendicular magnetic anisotropy is reduced at a room temperature and is increased at a temperature close to a predetermined reproduction temperature; and a reproduction layer opposed to the record layer through the switch layer to have a switched connection with the record layer by the switch layer.
