REPRODUCING METHOD FOR INFORMATION

摘要

PURPOSE:To provide a recording medium having high mass productivity, high recording density and excellent preservable property by heating a heat sensitive layer contg. an org. metal complex in the presence of an information pattern consisting of a material capable of accelerating the decomposition of the org. metal complex and reading out the information by an optical means. CONSTITUTION:This method consists in reading of the information recorded in the form of a thin metallic film pattern on the surface of the heat sensitive layer contg. the org. metal complex coated and provided on a substrate by the optical means by heating said heat sensitive layer in the presence of the information pattern consisting of the material capable of accelerating the decomposition of the org. metal complex disposed in contact with the heat sensitive layer. More specifically, this information recording medium is formed with the recording layer consisting of the thin metallic film pattern on either side of the heat sensitive layer by heating the heat sensitive layer contg. the org. metal complex under the conditions under which the pattern indicating the information is brought into contact with said layer. Such recording medium has the high sensitivity as well as excellent mass productivity and preservable property.
