Abstract
Abstract A packaged integrated information recording system has a plurality of information recording media radially arranged on a disk substrate. Each of the recording media comprises a liquid crystal recording medium including a liquid crystal-polymer composite layer with polymer balls filled in a liquid-crystal phase, stacked on a first electrode layer and a photoelectric sensor including a second electrode layer and a photoconductive layer formed on a transparent substrate. The liquid crystal recording medium and photoelectric sensor are stacked directly, or through an interlayer on each other while the liquid crystal recording layer and photoconductive layer are opposed to each other. The recording media may also be arranged in a row on a film substrate provided with feed holes on both side edges and received in a closable case such that it can be drawn. Alternatively, the recording media on a film substrate may be received in a packaging case having a window openable and closable by a shutter to unroll the film. Alternatively, the information recording media may be arranged in a row on a card substrate and fixedly received in a packaging case having window openable and closable by a shutter. The above arrangements allow images to be successively recorded by exposure to light and read.
