Abstract
In an image information recording apparatus, wherein a light beam is modulated by an information signal to effect recording on a recording medium, there is provided a light beam forming unit, a light beam modulator for modulating the formed light beam in accordance with an image information signal to produced first image information, an image forming lens for focussing the modulated light beam upon the recording medium, a recording medium sensitizer, a scanner for scanning the modulated light beam over the recording medium and additional image information which is overlaid on the first image information to produce an overlaid image on the recording medium.
