Abstract
A photosensitive film is scanned with nine laser beams for recording an image on the same. The subscanning pitch .DELTA.X.sub.1 is so determined as to be 4.5 P, where P is an alignment pitch of photospots formed by the laser beams. Scanning lines which belong to a 'front line group' and are scanned in a main scanning are spatialy alternated with other scanning lines which belong to a 'rear line group' and are scanned in the next main scanning.
