Typical apparatus according to this invention comprises a host interface for receiving digital data interface input from a host computer and delivering digital data interface output to the host computer, the interface output data comprising a function of the interface input data; an optical storage device (herein sometimes called a &ldquo;light drive&rdquo;) for receiving the interface output data from the host interface and providing optical radiation (i.e. radiation of wavelength in the range at least of about ultraviolet to at least about infrared) to each of a series of pixels in a region of a member comprising an effective concentration of photoreceptive material (PRM) and wherein the wavelength and intensity of the radiation in each pixel are functions of the interface output data received from the host interface; and a transmission medium for providing a datum signal from each pixel via the host interface to the host computer. The pixels typically are arranged at least predominantly in concentric rings on an at least approximately flat major surface of the member comprising the PRM.
