Abstract
A system for recording and reproducing a charge latent image in a recording medium has a transparent electrode (3), a photoconductive layer (4) on the electrode (3), a dielectric layer (8), a photoconductor layer (4) and a charge transfer suppressive layer (16). The system also includes a biasing element including a pair of electrodes (3, 19), a power source (10) for applying an electric field between the pair of electrodes, and an optical system (1) for directing an electro-magnetic radiation beam from an object (0) thereby forming an image thereof in the photoconductive layer (4). The reproducing system has a generating element (45, 48) for projecting the radiation beam toward the recording medium (41a, 41b), an element (20) for modulating the radiation beam, a first conversion element (55, 56) for converting the electro-magnetic radiation beam directed out of the path, an element (49a, 49b) for projecting the intensity modulated beam to an object, a second conversion element (57, 58) for converting the intensity modulated beam into an electrical signal, and an element (54) for directing the intensity modulated beam to the projecting element and the second conversion element.
