摘要： There are provided magnetooptic recording and reproducing method and apparatus of the Curie point writing type in which recording information can be read out by using a magnetic Kerr effect and the overwriting can be performed. At a position away from a laser irradiating section of a magnetooptic recording disk having first to third magnetic layers, there is applied a predetermined magnetic field which can magnetize the third magnetic layer in a uniform perpendicular direction and can magnetize the second magnetic layer in a uniform in-surface direction. Then, a recording bias magnetic field is applied to the laser irradiating section of the disk and a laser beam of a power such as to raise the temperature of the disk to a value near the Curie point of the first magnetic layer is simultaneously irradiated in accordance with a recording signal, thereby orienting the magnetizing direction of the first magnetic layer to a stable direction for the third magnetic layer without changing the magnetizing direction thereof. Or, a recording bias magnetic field is applied to the laser irradiating section of the disk and only a laser power so as to raise the temperature of the disk to a value near the Curie point of the third magnetic layer is simultaneously irradiated, thereby reversing the magnetizing direction of the third magnetic layer and magnetizing the first magnetic layer to a stable direction for the third magnetic layer.
