Electrostatic information recording medium and electrostatic informationrecording and reproducing method

Abstract From the Canadian patent

The present invention relates to an electrostatic information recording medium in which a charge retaining layer having high insulating properties is laminated on an electrode and an, electrostatic information recording/reproducing process wherein while said electrostatic information recording medium is positioned in opposition to a photosensitive member on which a photocondutive layer is laminated, the recording medium is subjected to information exposure with the application of voltage between both electrodes to accumulate electrostatic charges thereon depending upon the dosage of said information exposure and the electrostatic, inforamtion thus accumulated is reproduced by potential …
