<p>A magneto-optical recording medium incorporating a recording layer constituted by a multi-layered magnetic film composed of at least three magnetic layers. Domain walls of the magnetic layer adjacent to the portion irradiated with reproducing light are moved toward the center of the spot in a forward portion in a direction, in which the reproducing light spot is moved, so that a recording magnetic domain is enlarged, and movement of the domain walls of the magnetic layer adjacent to the portion irradiated with reproducing light is inhibited in a rear portion in the direction in which the reproducing light spot is moved. To inhibit movement of the domain walls of the magnetic layer adjacent to the portion irradiated with reproducing light, for example, insertion of a magnetic layer having a predetermined magnetic characteristic into a space between a displacement layer and a switch layer is required. <IMAGE></p> |
