Abstract
A scanning optical apparatus is used as a recording apparatus having an optical system and a mechanical system and effecting desired recording on a photoconductor by irradiation of a beam. The apparatus comprises marks confirming the beam scanning position on the photoconductor, an error detecting unit for detecting the error of the scanning position from the optimal scanning position, which error is due to an optical factor or a mechanical factor, and a control unit for suitably correcting the scanning position of the beam in real time on the basis of a signal representing the detected error.
