SELECTIVE ERASURE OF IMAGE RECORDING DEVICES ABSTRACT OF THE DISCLOSURE Method and apparatus for selectively erasing informa- tion formed on the surface of image recording device which deforms when illuminated in the presence of an electrostatic field applied thereacross. The image recording device, com- prising a layered structure consisting of a conductive trans- parent substrate, a photoconductive layer, a deformable elastomer layer and a deformable electrode, is initially raster scanned by information containing light through the photoconductor layer with voltage applied between the conductive electrodes whereby the elastomer and deformable electrode are deformed in accord- ance with the input information. For selective erasure, the voltage is removed and the device is short-circuited. With the device shorted, the area to be erased is scanned with the spot of light. The short is then removed and the voltage re- applied, the remainder of the information except for the area erased, being restored. Additional information can be written in the erased area if desired.
