摘要： Provided is a magnetic domain wall displacement magneto-optical recording medium having a preferable reproducing signal characteristic. The magnetic domain wall displacement magneto-optical recording medium includes at least a magnetic domain wall displacement layer, a switching layer, and a recording layer, in which magnetic coupling between recording tracks is disconnected. An in-plane magnetized film layer is further provided adjacent to the surface of a recording layer opposite to a side of the recording layer facing the magnetic domain wall displacement layer.

摘要： A domain-wall-displacement-type magnetooptical recording medium is provided in which a floating magnetic field from a surrounding portion that operates on a recording/reproducing portion is suppressed. The recording medium includes a displacement layer having a composition such that rare-earth-element sub-lattice magnetization is dominant at room temperature, a switching layer, a memory layer, and a magnetization compensation layer in which iron-family-element sub-lattice magnetization is dominant at room temperature, for suppressing generation of a stray magnetic field at a temperature near room temperature.

摘要： A magneto-optical recording medium has a domain wall displacement layer, a recording layer for accumulating information and a switching layer arranged between said domain wall displacement layer and said recording layer and having a Curie temperature lower than those of the latter two layers. The domain wall displacement layer, the switching layer and the recording layer are coupled by exchange coupling at temperature not higher than the Curie temperature of the switching layer. The saturation magnetization of the domain wall displacement layer and the recording layer are in opposite directions to each other when the layers are coupled by exchange coupling at a temperature close to the Curie temperature of the switching layer.
