A novel information recording medium is provided which records information upon the application of thermal energy, reads the recorded information by detecting the value of photoelectric current generated by light applied to the information recorded portion, and can realize multi-valued information recording or analog information recording.
The information recording medium comprises: a pair of electrodes; and a liquid crystal material filled into a gap between the electrodes, the liquid crystal material having a property such that the charge-transport properties are varied according to the phase transit between a plurality of stable liquid crystal phases of the liquid crystal.
本发明提供了一种新型信息记录介质,该介质可在热能作用下记录信息,通过检测施加到信息记录部分的光产生的光电流值来读取所记录的信息,并可实现多值信息记录或模拟信息记录。
信息记录介质包括:一对电极;以及填充在电极间隙中的液晶材料,该液晶材料具有这样一种特性,即电荷传输特性随液晶的多个稳定液晶相之间的相位转换而变化。
