ABSTRACT:
As shown in FIG. 1a, the information recording medium of the present invention includes an information recording layer on an electrode layer (13), said recording layer made up of a resin system (11) having liquid crystal phases (12) dispersed and fixed therein. In said recording layer, the refractive index of light through said resin system is such chosen as to be substantially coincident with the refractive index of light through the liquid crystal material which is being oriented by an electric field, whereby electrostatic information can be recorded and stored on the recording medium as visible information and the recorded and stored information can be reproduced at any desired time. The present recording medium can also be recycled, if the information recorded on it is erased.
