ABSTRACT:
A light beam scanning device and method which a light beam scanned over a moving recording medium in a pattern of parallel scanning lines. The light beam is scanned in a reciprocating manner in a main scanning direction perpendicular to the direction of movement of the recording medium and perpendicular to an auxiliary scanning direction. The beam is deflected in the auxiliary scanning direction in synchronization with the reciprocal motion of the beam in the main scanning direction by an amount so as to produce a pattern of parallel scanning lines.
