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.
Claims2
An information recording medium, comprising an information recording layer including a resin member with liquid crystal phase dispersed therein, said information recording layer fixed on a first electrode layer and selected in such a manner that a refractive index of said resin member is approximately consistent with a refractive index of said liquid crystal phase when an electric field is applied and a photosensitive layer laminated on a second electrode wherein said information recording layer and the photosensitive layer are brought into planar contact with each other and wherein said information recording layer is fixed on the first electrode via an electric charge injection prevention layer on the information recording layer.
