ABSTRACT:
A light orientation film and a liquid crystal thin film are formed adjacent to each other. Light is irradiated to the light orientation film and the liquid crystal thin film, so as to cause the light orientation film to be orientated while viscosity of the liquid crystal thin film is lowered by a temperature increase by the light irradiation, so that an intermolecular force on the boundary between the light orientation film and the liquid crystal thin film causes the liquid crystal molecules in the liquid crystal thin film to the orientation of the light orientation film. By this orientation of the liquid crystal molecules, recording information is maintained. Thus, it is possible to realize a sufficient signal amount while using the light orientation film as well as to obtain a thermal stability and a stability against light irradiation.
