<p>PURPOSE:To easily transfer intrinsic information in a card to another recording medium without applying a plastic machining, e.g. embossing, to a card substrate by a method wherein after a photosensitive recording medium is overlapped on an intrinsic information recording part where intrinsic information in the card is recorded using a light shielding member on a transparent substrate, only the intrinsic information recording part is irradiated with light. CONSTITUTION:An intrinsic information recording part 3 in an optical card 1 is formed by solid printing a black ink as a light shielding member 7 on a substrate 4, and thereon characters ABC as intrinsic information are recorded by removing the corresponding light shielding member 7 by engraving. When the optical card 1 is used, the writing or reading of information to/from an optical recording part 2 is conducted similarly to a conventional optical card. When a certification of using the card is to be recorded, the optical card 1 is placed on a photosensitive recording medium 8, such as diazo photosensitive paper, and thereon irradiated with an ultraviolet light by an ultraviolet light emitter 9, whereby the characters ABC are transfer recorded on the photosensitive recording medium 8. In addition, a light shielding board 10 is placed on the optical recording part 2 to prevent the break of the information recorded on the optical recording part 2.</p> |
