Abstract:
1. A magneto-optical recording medium, comprising: a substrate; and a reproducing layer and a recording layer provided on the substrate, wherein: a recording magnetic domain is provided in the recording layer by heating the recording layer by irradiation with light and applying a recording magnetic field to the recording layer so that information is recorded in the recording layer; the recording layer is a magnetic film having magnetic anisotropy in a direction perpendicular to the film surface, and the magnetic film holds the recording magnetic domain formed therein; the magnetic domain recorded in the recording layer is transcribed onto the reproducing layer in a vertical magnetization direction and subsequently disappears substantially automatically because of a shrink force of the reproducing layer; and a coercive force of the reproducing layer is smaller than a transcribing magnetic field from the recording layer to the reproducing layer in a temperature region greater than or equal to a reproducing and transcribing temperature at which the magnetic domain of the recording layer is transcribed onto the reproducing layer.
