Optical information recording system
专利汇可以提供Optical information recording system专利检索，专利查询，专利分析的服务。并且PURPOSE: To make it possible to utilize a silver salt print as a reliable information medium by reading information by the light within a wave length range, where the silver salt is not sensitized, before development and fixing after the silver salt is blackened by photochemical reaction to record information and developing and fixing the silver salt after errors are corrected.
CONSTITUTION: Ar laser from Ar laser tube ARR is turned on and off on a basis of information signals by light modulator LM, and simultaneously, a silver slat emulsion material is applied to a photosensitive material. Then, recording medium MD is moved in a prescribed direction by motor M, and medium MD is exposed to light properly by a light beam, and the exposed part is blackened to write information. Next, medium MD is scanned by laser from He-He laser tube HNR, and it is detected by photo diode PD whether the beam passes through the erroneous medium or not. If errors are detected in written information, information is written again by Ar laser, and finally, development and fixing are performed the known method.
