ABSTRACT:
The present invention relates to a polymer dispersion liquid crystal recording medium containing liquid crystals dispersed and fixed in resin, as well as to a method and an apparatus for reproducing information. In particular, when a medium as shown in FIG. 6 is used, the information recorded on the liquid crystal layer can be read with sufficient contrast by making the photoconductive layer (13) transparent to blue or ultraviolet light, and by making the wavelength of the reading light match the wavelength of the blue or ultraviolet light. When image reading is performed as illustrated in FIGS. 3 and 7, a white light source is used as light source (4), and a filter (5) is placed between light source (4) and the liquid crystal medium (20); thus, only blue or ultraviolet light enters the liquid crystal medium. After passing through the liquid crystal medium (20), the light is converted to an electric signal by a photoelectric converter (6).
