Electrostatic recording medium with elongated conductive segments

摘要

An electrostatic recording medium having an insulating base, a conductive layer on the base, and a dielectric layer on the conductive layer. The conductive layer is divided into a plurality of segments arranged in a direction in which recording electrodes are aligned with each other, so that when associated electrodes of all the arrays of recording electrodes on one side of the recording medium are selected in common with each other and one of complementary electrodes on the other side of the recording medium is selected, a discharge occurs only in the recording electrode disposed above the selected complementary electrode. Each conductive layer segment is formed with at least one conductive portion extending through the insulating resin base and capable of coming into contact with one of the complementary electrodes. An intermediate resistance layer may be provided between the conductive layer and the dielectric layer for preventing the formation of a short circuit through the dielectric layer due to the existance of pin-holes or other defects.
