Abstract
A storage target includes a dielectric storage medium in the form of a relatively rigid sheet of insulating material having high density, such as a single crystal sheet of sapphire. A film electrode is formed, as by vapor deposition of nickel or like conductive material, on one of the surfaces of the storage medium. An array of openings are defined by and extend through the storage medium and film electrode. In some embodiments the collector electrode of a direct-view storage tube is formed on the other surface of the storage medium, also as by vapor deposition of nickel and subsequent etching.
