Recording medium, recording apparatus and recording method

摘要

The present invention provides a recording medium having a plurality of charge accumulating regions each containing a first material capable of accumulating an electric charge and a photoconductive region containing a second material whose conductivity is increased by light absorption, a recording apparatus including such a recording medium, and a method recording information on such a recording medium. In the present invention, information is recorded on the recording medium by irradiating the photoconductive region with light and by injecting an electric charge into the charge accumulating region via that portion of the photoconductive region which is irradiated with light.
