    • The electrostatic data recording medium (110) of the invention comprises an electrode layer (113) and a charge-holding layer (111). The method of laminating the charge-holding layer (111) and the structure of the layer are improved. Further, the electrostatic data are converted into visible or positional data. Thereby, the medium has excellent characteristics of data holding, and the electrostatic data can be stored for a longer period of time. According to the electrostatic data recording method of the invention, the electrostatic data recording medium (110) is so disposed as to face a photosensitive member (1) having a photoconductive layer (9) on an electrode (7), image exposure is carried out while a voltage is applied across the electrodes (113) and (7), and electrostatic data corresponding to the image exposure are recorded in the electrostatic data recording medium (110). The electrostatic data recorded in the charge-holding layer (111) can be easily reproduced by reading the surface potentials, to amplify and output the signals, or by an electro-optical method, or by developing with toner. The electrostatic data recording medium (110) of the invention has storage capacity with a high data density of 8 x 10 bits/cm . The electrostatic data recording method which uses a photosensitive member makes it possible to accomplish two-dimensional data-recording, and to record analog, digital, picture, voice and (0, 1) data, and to realize the application electrostatic data recording cards, etc.
    • 本发明的静电数据记录介质(110)包括电极层(113)和电荷保持层(111)。 层叠电荷保持层(111)的方法和层的结构得到改善。 此外,静电数据被转换成可见或位置数据。 因此,该介质具有优异的数据保存特性,并且可以将静电数据存储较长时间。 根据本发明的静电数据记录方法,静电数据记录介质(110)被布置为面对在电极(7)上具有光电导层(9)的感光构件(1),进行图像曝光 同时在电极(113)和(7)之间施加电压,并且对应于图像曝光的静电数据被记录在静电数据记录介质(110)中。 记录在电荷保持层(111)中的静电数据可以通过读取表面电位,放大和输出信号,或通过电光学方法或通过用调色剂显影来容易地再现。 本发明的静电数据记录介质(110)具有8×10 8位/ cm 2的高数据密度的存储容量。 使用感光元件的静电数据记录方法可以实现二维数据记录,并记录模拟,数字,图像,语音和(0,1)数据,并实现应用静电数据记录卡, 等等
