ABSTRACT:
The camera or data recording apparatus (30) consists of an optical system for creating a data record on a photosensitive medium and includes a laser (36) for generating a light beam and mirrors (62, 72, 74 and 82) for transmitting the light beam to a final light beam path (56e) which is rotated about an axis (63) parallel spaced from the final light beam path (56e). Further the camera (30) includes an assembly (38) for shaping and focusing the light beam to have a bar shape cross section which is directed to the rotating final light beam path and imaged onto a photosensitive medium (86). A modulator (58, 60) modulates the light beam from the laser (36) intermittently to image or record light beam bar shape cross sections defining data in an arcuate path (14) on the photosensitive medium (86), a computer (32) controls the modulator (58, 60) and a carriage (88) is provided for moving the photosensitive medium (86) toward and away from the axis (63) about which the final light beam (56e) rotates.
