Abstract: Apparatus is provided for using a dry process photographic medium of the type described in Copending application Ser. No. 510,153 for recording data. The photographic medium includes an electrically conductive base which responds to electric power to produce developing heat internally. The apparatus of the invention includes electrodes in the form of rods, or rollers, for example, across which the medium is drawn, and electronic circuitry connected to the electrodes for introducing a controlled electric current flow through the base of the medium between the electrodes to develop latent images previously exposed on the medium, by the generation of electric power directly in the base.
