摘要： A magneto-optic recording and regenerating process and the device using it in accordance with the present invention are intended to magnetize the magnetic, or magnet, film of a disk parallel to the plane of the magnetic film to record or erase information. When regenerating information, light beams whose incident plane is substantially perpendicular to the direction of magnetization of the recording medium is applied to the disk, so that the recorded information is regenerated dependent on the light intensity of reflected light obtained in response to the direction and magnitude of magnitization of the disk. Additionally, the magneto-optic disk includes a magnetic film having a coercive force smaller than the saturated magnetization at room temperature, so that irradiating light beams elevate the temperature of the magnetic film but not up to its Curie temperature. Information is then recorded on or erased from the magnetic film with its coercive force decreased by the elevated temperature.
