    摘要: An optical deflection device includes an optical deflection element having a pair of transparent boards arranged in a mutually opposing manner. A liquid crystal layer is filled between the boards and forms a chiral smectic C phase. An orientation film orients liquid crystal molecules in the liquid crystal layer in a substantially perpendicular direction with respect to the liquid crystal layer. Electrodes generate an electric field in a substantially parallel direction with respect to the liquid crystal layer. A first voltage application part applies, to the electrodes, an ac voltage of a deflection frequency switching the optical deflection direction of the optical deflection element. A second voltage application part applies, to the electrodes, an ac voltage of a higher frequency than the deflection frequency. A stop process part causes the second voltage application part to apply the ac voltage of the higher frequency than the deflection frequency after causing the first voltage application part to apply the ac voltage of the deflection frequency, when stopping an operation of switching the optical deflection direction of the optical deflection element.

    摘要: A magneto-optical recording medium includes a recording layer which is composed of A memory layer comprising a ferromagnetic layer with perpendicular anisotropy, and an auxiliary layer comprising antiferromagnetic layer which exhibits an antimagnetic phase at room temperature, and a ferromagnetic phase at temperatures near the Curie temperature of the memory layer which is higher than room temperature, because of the occurrence of magnetic phase transformation, with the memory layer and the auxiliary layer being overlaid. A magneto-optical recording method using this magneto-optical recording medium is described.

    摘要: A three-dimensional magnetic memory medium which comprises a substrate, a plurality of magnetic layers and a plurality of nonmagnetic layers. The magnetic layers and the nonmagnetic layers are alternately stacked one above the other on the substrate. Each magnetic layer comprises a transfer area, wherein assuming that n is a positive even whole number, the (n-1)th magnetic layer (the 3rd layer, the 5th layer, the 7th layer, . . .) has a transfer pattern different from that of the nth magnetic layer (the 2nd layer, the 4th layer, the 6th layer, . . .). An uppermost magnetic layer is used as a signal writing area and as a signal reading area. A position corresponding to a signal "1" and a position corresponding to a signal "0" are arranged in the signal writing area at a position superposed on a position of "1" and on a position of "0" in a transfer pattern of the (n-1)th magnetic layer, respectively. A guide line is provided in the signal writing area so that a magnetic bubble is movable between the position of a signal "1" and the position of a signal "0" along the guide line.
