Abstract
An optical system for use in a flying spot scanning apparatus. The optical system includes a laser tube, an optoelectronic integrated circuit which divides a laser beam into a plurality of beams and individually modulates the beams, a focusing lens for focusing the beams, a deflection mirror for reciprocatingly deflecting the beams to scan a recording medium, a concave mirror receiving the beams thereon, and a recording medium disposed optically behind the concave mirror. The recording medium is fed in a predetermined direction while the beams are scanned across the recording medium.
