    摘要: The CGH (computer generated hologram) readout section (4) reproduces an image of the CGH (28), which is formed in the data storage area (52) of the crude card (26). The CGH certifying section (5) judges whether the card is genuine or fake and obtains an ID (identification) information. In a case that the card is genuine, the ID information is supplied to the data processing section (6). The data processing section (6) inputs a personal information of a person to be a cardholder and also inputs a face picture of the person. These data are registered in the database (2) in response to the ID information. A part of or all of the personal information is outputted to the IC reader/writer (8) and written into the IC module (53). Further, a part of the personal information and the face picture are outputted to the color printer (7) as a printing information and printed on the surface of the crude card (26). Then the personal ID card (51) can be issued after forming a protection film over the printed surface of the card.

    摘要: A storage medium has at least one diffraction grating. The diffraction grating is formed as a holographic interference fringe pattern. The pattern is formed as it two-dimensionally diffracts an incident light beam in a plurality of directions or one-dimensionally diffracts an incident light beam in a direction. A combination of such patterns and also a plurality of rows of such patterns on the storage medium are available. A light beam is radiated to the storage medium. The light beam diffracted in the direction(s) is detected by a photodetector, such as a CCD device, that generates a signal carrying data stored as the holographic interference fringe pattern. The signal is then decoded by a processor to reproduce the data.
