ABSTRACT:
The present invention provides an information recording medium having a liquid crystal phase, which can be repeatedly used. In an information recording medium where an information recording layer comprising a liquid crystal phase and a resin phase is laminated on an electrode, a mixture containing a smectic liquid crystal having good memory property and a liquid crystal having low memory property is used as the liquid crystal phase, the information recorded on the liquid crystal disappears as time elapses without being heated and the information recording medium can be repeatedly used for further information recording.
