1. An apparatus for reproducing information recorded on an information recording medium comprising an information recording layer having a liquid crystal layer and a UV-setting resin layer and arranged on an electrode layer, such that information is recorded on an information recording medium comprising an information recording layer having a liquid crystal layer and a UV-setting resin layer and arranged on an electrode layer, wherein an outer surface of said information recording layer is formed only by UV-setting resin, wherein a photosensitive member having a photoconductive layer is placed face-to-face to the information recording layer on a contact or non-contact basis, and information is written onto said information recording medium by light exposure under voltage application, whereby said information recording layer has a characteristic of transmitting ultraviolet light or blue light within a wavelength range of 320 to 500 nm, where an outer surface of said information recording layer is formed only by UV-setting resin,wherein the apparatus comprisesan illuminating optical means for irradiating ultraviolet light or blue light within a wavelength range of 320 to 500 nm onto the information recording medium anda photoelectric converter for detecting transmission light transmitted by the information recording medium, wherein the photoelectric converter has a window made of window material;

  • wherein a smectic liquid crystal with a memory property is used in the liquid crystal layer.
