Abstract
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 is 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 laye…
