Abstract

PURPOSE:To simplify the production process and prevent erroneous sticking, positional slippage, deficient sticking, etc. of an indication label, by forming a protecting layer on the surface of a radiation reflective layer by printing the ondication on the plane part of a base material. CONSTITUTION:A recording face 2 where information is recorded discontinuously and a plane part 4 are formed on the surface of a light transmitting base material 1, and a radiation reflective layer 2 is provided on the surface so that the recording face 2 can be read optically. A protecting layer 13 is formed on the surface of the radiation reflective layer 2 of this optical recording medium by printing, and simultaneously, indications of items concerning information are printed on the suface of the plane part 4. For example, a reflective layer 5 is formed on the surface of a mold formed base material 1 by vacuum vapor- deposition of Al. Next, a plate 7, where an indication 8 is marked in the center and a recess part 9 is marked on the outside circumferential part of the center part, and a pad 11 are used to perform a pad printing. and thus, an indication 14 due to an ink 10a and the protecting layer due to an ink 10b are formed simultaneously.
