STORING METHOD FOR OPTICAL SENSOR

摘要

PURPOSE:To obtain an optical sensor and an information recording system based thereon which suffer less degradation due to aging and are free from image noises. CONSTITUTION:This optical sensor is one for recording information that is used to form information to be recorded in an information recording medium; the optical sensor is obtained by forming a photoconductive layer 14, or a charge generating layer 14' and a charge transfer layer 14'' to form the photoconductive layer 14, on an electrode layer 13 and 13' formed on a substrate 15. The thus manufactured optical sensors are stored in a dark place at a low humidity (relative humidity: 60%) until use in information recording systems.
