ABSTRACT:
A high resolution recording medium is provided which employs at least two layers of inorganic material which act as filters for two different colors of visible light. In one embodiment, microphoto lithography techniques are used to create microinterference filters in the desired patterns on a glass substrate. Recording media constructed according to this invention exhibit increased stability with respect to time and improved resistance to light and heat damage as compared with prior art recording media employing organic dyes.
