摘要： PURPOSE:To obtain a recording medium which permits semi-permanent preservation of record and rewriting by consisting a recording layer of a specific thermotropic cholesteric mesomorphic glutamic acid ester copolymer. CONSTITUTION:The film of the recording layer consists of the thermotropic cholesteric mesomorphic glutamic acid ester copolymer expressed by the formula and forms hardly no liquid crystal structure at about an ordinary temp. without having the power to selectively reflect specific light. However, said film forms a cholesteric liquid crystal in a liquid crystal forming temp. region when the temp. thereof is increased by the irradiation of laser light thereon. The irradiated micro-region is quickly cooled and the cholesteric liquid crystal structure is fixed after the laser light moves. The record is thus held. The recording layer has the power to selectively reflect the light of a specific wavelength according to the cholesteric pitch when the cholesteric structure is once formed and therefore, the recording conditions are preliminarily so set that the wavelength conforms to the wavelength of the reading out laser light. The reading out is thereby easily executed by the difference in the reflectivity or transmitting.

摘要： PURPOSE:To raise the shelf life and decrease the deterioration due to deletion and regeneration possible, by a method wherein the light absorption electrode layer has the layer composed of phthalocyanine and the liquid crystal is of high molecular liquid crystal. CONSTITUTION:The substrate is composed of glass, various resins such as acryl, polycarbonate, etc., various photosensitive resins, various metals, etc., and the electrode layer is formed on its surface. This electrode layer possesses both functions of electrode layer and light absorption layer and phthalocyanine is used for the light absorption agent. The liquid crystal is of high molecular liquid crystal and the high molecular liquid crystal has liquid crystal group as principal chain or side chain. Its mean molecular weight is 500min. Thereby, the shelf life is extremely raised and the deterioration due to deletion and regeneration is strikingly decreased. Then, the recording sensitivity and the S/N ratio of reading out are raised, too.

摘要：本発明の光記録媒体は、ジアリールエテン化合物等の環状電子反応型のフォトクロミック性化合物を含む側鎖型高分子液晶、または、該フォトクロミック性化合物が結合したモノマー単位を高分子鎖内に有する側鎖型高分子液晶からなる。光記録を行うためには、一軸方向に配向されたこの光記録材料を用いる。光記録は、この光記録材料に側鎖型高分子液晶の透明点近傍の温度でフォトクロミック性化合物の構造を変化させる波長の光からなる情報信号を照射することによって、側鎖型高分子液晶の分子配向が変化して情報信号が記録される。また、記録の読み出しは側鎖型高分子液晶のガラス転位点未満の温度において、側鎖型高分子液晶の分子配向変化による複屈折率の変化を入射光の偏光の変調として読み出すことによって行われ、その際光記録に用いた光と同一波長の光を使用して記録の読み出しを行っても、この光記録材料に記載されている情報信号は破壊されることはない。
