Method and apparatus for reproducing information from a magneto-optical recording medium |
摘要 |
A magneto-optical recording medium includes a substrate and a reproducing layer and a recording layer provided on the substrate. A method for reproducing information from the magneto-optical recording medium includes increasing the temperature of the magneto-optical recording medium irradiated by laser light and included in an inside part of a light spot to a temperature range including a temperature at which the saturated magnetization of at least the recording layer or the reproducing aid layer is maximized, and reproducing the information only from a temperature region within the light spot where the information can be transcribed from the recording layer by a magnetic coupling force between the recording layer and the reproducing layer, by transcribing the recording magnetic domain from the recording layer onto the reproducing layer.
