ABSTRACT:
A light beam recording system in which the beam is deflected after passage through a focusing element to scan a recording medium. An optical image surface correction system is employed between the deflector and recording medium for correction of the curvature of the field in the main scanning direction. The optical correction system includes an aspherical surface and deviation from a paraxial generating spherical surface to the aspherical surface.
