摘要: An optical recording material comprising (I) a substrate, (II) layer provided on said the consisting of light transmissive portions and screening portions, (III) reflective metallic thin film layer; as well process therefor. The invention also includes an card substrate. In cases card, it is possible to readily carry out high density recording, alternation written informaton difficult, information can be read basis difference in reflectivity.
