Claim One:
1. A method of addressing electrical information into an electrical information storage member, comprising, providing an electrical information storage memer comprising a solid layer of substantially electrically insulating material containing a layer of particulate electrically photosensitive material, a semiconductor layer contacting one surface of said layer of substantially electrically insulating material, a substantially transparent electrode layer of electrically conductive material contacting the opposite surface of said layer of substantially electrically insulating material and a plurality of electrode pairs contacting said semiconductor layer, substantially uniformly exposing the entire layer of electrically photosensitive material with activating electromagnetic radiation, and placing an electrical field across the thickness of the member in desired areas of the member by biasing the electrodes of selected electrode pairs with respect to said electrode layer, thereby addressing electrical information into said desired areas corresponding to said selected electrode pairs.
