ABSTRACT:
Apparatus to record image information, presented in the form of electrical input signals, as complete half-tone images in a spiral centered about the center of a plate-shaped image record and to make sound recordings, from electrical input signals, presented as an optical sound track aligned with and adjacent to the line of half-tone complete images, and to record optical control tracks for controlling playback of the record adjacent to and aligned with the spiral of the half-tone complete images. The apparatus includes digital to analogue convertors; a Read Only Memory; an image sound line Random Access Memory, wherein, in a desired order and line-by-line, electrical input impulses, representing image and sound information, after undergoing analog to digital conversion, are recorded together with ROM information to form the control tracks; a laser producing an output light beam; a modulator modulating the light beam with information coming, after digital to analog conversion, from the image sound line Random Access Memory; a sweep deflecting unit, whereby the modulated laser beam, on being deflected thereby is swept along a line on a light-sensitive layer at the time of recording; an objective focussing the laser beam; a record turntable; and a carriage rotatably supporting the record turntable that supports an image record having a light-sensitive layer, whereon the light beam, after being focussed in the objective, is pointed for the line-by-line recording of the information taken from the image sound line Random Access Memory.
