Abstract
PURPOSE:To enable the rapid and exact recording by a simple method at the time of recording and reproducing information by forming ruggedness of information recording patterns to an optical recording part and laminating a light reflecting material or optical recording material on a base material so as to cover the rugged parts. CONSTITUTION:The optical recording part 2 is formed on the specified base material 1. The optical recording part 2 is formed with a conductive layer 2a, a photoconductive layer 2b as well as a light reflecting material layer or optical recording material layer 2c in this order. The information to be recorded is formed in the form of rugged patterns on the surface of the light reflecting material layer or the optical recording material layer 2c. Identification of the recorded information is executed by detecting the difference in the optical characteristics, i.e., reflectivity, phase difference, etc., of the reflected light of the respective parts at the time of reading the information. The information patterns are thus extremely exactly, finely and rapidly formed by laser light, etc.
