Abstract
A novel information recording device scans and exposes a photosensitive medium for electrophotography by information light by the use of a scanning light forming optical integrated circuit (IOS) including a light deflecting portion and a condensing thin film lens on a thin film waveguide path. The device, as compared with prior art information recording devices using beam spot scanning, is very compact and capable of high-speed recording and can realize a low cost of manufacture.
