Abstract
An optical printer includes magneto-optical storage elements (light switching elements) formed on a carrier body (substrate) of comparatively small dimensions. The light switching elements LZ on the substrate T are combined so as to form groups M which are separated from one another by an equidistant space a. Each group M is associated with a self-focusing lens LS so that the distances between all image points of a plurality of groups M on a record carrier Z are equal.
