    • An information recording system including a photoelectric sensor being semiconductive and having a photoconductive layer stacked on an electrode, and an information recording medium having an information recording layer stacked on an electrode so that information can be recorded on the information recording layer by an electric field or electric charge. The photoelectric sensor and the information recording medium are disposed to face each other, and information exposure is carried out with a voltage being applied between the two electrodes, thereby enabling information to be recorded on the information recording medium. The photoconductive layer of the photoelectric sensor is capable of amplifying an electric field or electric charge given to the information recording medium, so that the intensity of electric field or the amount of electric charge given to the information recording medium can be increased to a level higher than the light energy actually applied. Accordingly, information recording of high sensitivity can be performed even if information exposure is carried out with a relatively small light energy.
    • 一种信息记录系统,包括半导体的光电传感器和层叠在电极上的光电导层,以及信息记录介质,其具有堆叠在电极上的信息记录层,以便可以通过电场将信息记录在信息记录层上,或 电荷。 光电传感器和信息记录介质被设置为彼此面对,并且在两个电极之间施加电压来执行信息曝光,从而使得能够将信息记录在信息记录介质上。 光电传感器的光电导层能够放大给予信息记录介质的电场或电荷,从而可以将给予信息记录介质的电场强度或电荷量提高到更高的水平 比实际应用的光能量。 因此,即使以较小的光能进行信息曝光,也可以进行高灵敏度的信息记录。
