Photoelectric sensor, information recording system, and information recording and reproducing method

摘要

In a photoelectric sensor that enables information to be recorded on an information recording medium at an intensity amplified to a level higher than that of a current induced by information exposure and allows conductivity to remain maintained by a continued application of voltage even after termination of the information exposure, so that information can subsequently be recorded on the information recording medium, a photoconductive layer contains a substance that emits fluorescence in a wavelength region in which a charge generation substance-containing layer absorbs light, so that color images can be well recorded on the information recording medium. Also provided is an information recording system using such a photoelectric sensor.
