摘要： 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.

摘要： In an information recording and reproducing method and apparatus, a piece of picture image information is recorded as an analog quantity or a digital quantity on an information carrying medium (3) in a planar manner at a high density, charge potential is read for outputting electric signals to correspond to the recorded picture image information, and then the outputted signals are printed out by means of various display units or output devices with high quality and high resolution as well as ease processing of the information. The information carrying medium (3) provides a long period of storage of information, and enables stored picture image information to be repeatedly reproduced with a picture quality according to need. Particularly, it is possible to read and output local potential of an information carrying medium (3) with predetermined scanning density at a desired time, and so pictures of high quality may be output as a silver salt photograph is taken and reproduced by optically scanning the film. Thus, the present invention may be applied to a wide field including photographing, copying and printing.
