摘要:
There is provided a recording medium for recording information in a form of a charge latent image. The recording medium comprises, at least, an electrode through which an electro-magnetic radiation beam passes, a photo-conductive layer (hereinafter abbreviated in a PCL) whose resistance varies when the beam is applied thereto and an insulation layer (hereinafter abbreviated in an IL), the electrode and the layers being laminated to each other. There is further provided an apparatus for recording an image as a charge latent image on the medium described above. The apparatus comprises a guide for guiding an electro-magnetic radiation beam through the electrode, an auxiliary electrode arrangeed to face the madium so as to interpose the PCL and the IL between the electrodes and an unit for applying an electric field across the electrodes. There is still further provided an apparatus for reproducing information prerecorded as a charge latent image on the medium. The apparatus comprises a pickup having a plurality of voltage detection electrodes confronting the charge latent image recorded on the medium, a generator for projecting an electro-magnetic radiation beam toward the medium along a path and a reading head disposed in the path and having at least a photo-modulation layer facing the medium so as to be subject to charge of the charge latent image prerecorded on the medium.
