Information recording media enable images to be recorded and reproduced with high resolution, wherein oozing of liquid crystal material thereof is prevented and the information recorded without unevenness. A first recording medium has an information recording layer comprising a liquid crystal phase and an ultraviolet curing resin phase. The information recording layer is stacked on an electrode layer provided on a substrate by coating a mixed solution of liquid crystal and ultraviolet curing resin material on the surface of the electrode layer and then irradiating the coating by irradiation with ultraviolet rays, thereby forming a cured skin layer of the resin material on the outer surface of the information recording layer. A second recording medium has a transparent electrode layer additionally provided on the information recording layer of the first recording medium. A third recording medium has an electrode layer, a photoconductive layer, an information recording layer, and an electrode layer, in successive order. A fourth recording medium has a transparent insulating layer or semiconductor layer interposed between the photoconductive layer and the information recording layer of the third recording medium. According to an information recording and reproducing method employing the first recording medium, a gradually increasing voltage is applied between a photosensitive member and the recording medium. As a result, the effective voltage applied to the liquid crystal layer can be raised, enabling increased modulation, improved contrast and responsiveness.
An information recording medium wherein an information recording layer which comprises a liquid crystal phase and an ultraviolet curing resin phase is provided on an electrode layer, said information recording layer being formed by coating a mixed solution of a liquid crystal and an ultraviolet curing resin material on a surface of said electrode layer and then irradiating said coating by irradiation with ultraviolet rays so as to form a cured skin layer of said ultraviolet curing resin material on an outer surface of said information recording layer.
