摘要： A certification card such as ID card or the like includes a hologram and an optical recording portion. Hologram is such that an amplitude and a phase of a light wave emitted from an object are recorded and an image of the object is rebuilt by emitting light to reproduce of an amplitude and a phase of the thus emmited light. An optical recording technique for use with the card employs data pits which are formed on an optical reflective surface of an optical recording layer. The thus formed data pits are detected by difference in optical reflectivity from the data pits when the object is illuminated by laser beam so that data are read. The card is constituted by adhering a card front substrate to a card rear substrate, and hologram and optical recording portion are formed between the card front substrate and the card rear substrate. The certification card is difficult to falsify and alter and, therefore, has high safety.

摘要： An optical recording medium includes a silver grain layer containing a large number of blackened fine silver grains and a coloring matter layer containing coloring matter on a base board and the coloring matter has an ability of absorbing near-infrared ray. When laser beam having a density of optical energy more than a boundary which represents a threshold with respect to the density of optical energy is radiated to the optical recording medium, a part of the latter is deformed to form a plurality of convexities which will be utilized as optical recording pit. The recording pits formed in this way are detected by presence or absence of reflection of radiated light whereby the content of optical recorded informations can be read. The optical recording pits are not deformed further irrespective of how long a reading light comprising laser beam having a density of energy less than the threshold is repeatedly radiated to the optical pits. Accordingly, any reduction of S/N ratio of a signal does not take place as time elapses.

摘要： In an optical card, a card substrate has its rigidity which is sufficient to handle the card substrate independently. The card substrate has a first side which serves as a reading side upon which reading light is incident. An optical-data recording section includes a light-reflective pattern. The optical-data recording section is arranged on one of the first and second sides of the card substrate. Optical data incident upon the optical-data recording section toward the reading side of the card substrate is recorded by the optical-data recording section. A shielding layer is arranged on one of the first and second sides of the card substrate, for shielding the optical-data recording section from a viewer's field of view. The shielding layer has its transmission characteristic with respect to the reading light, which is sufficient to shield light within a visual range and to enable reading of the optical-data recording section.

摘要： A technique of an optical card having high information recording density. A specially superior writing characteristic is required for an additional recording optical card among optical cards. In the case where the optical card of additional recording type is closed, reduction in the writing characteristic is observed. In this invention, a sensitizing layer (50), which serves as escape for molten recording material at writing, is provided in rear of an optical recording section (30), so that an optical card is produced which is superior in both environmental resistance and writing ability. The sensitizing layer (50) is made of self-oxidizable or thermoplastic resin and an absorbing agent dispersed in the resin. The absorbing agent cooperates with the resin not only to improve a writing characteristic, but also to improve design ability and reading ability of the card.

摘要： An optical or magneto-optical recording card is produced using a transfer type optical or magneto-optical recording medium. The transfer type optical or magneto-optical recording medium comprises a base film, a peeling layer, an optical or magneto-optical recording layer and a light permeable adhesive layer which are successively superimposed one above another to constitute a layered structure. A protective layer is adhered to the transfer type optical or magneto-optical recording medium with the aid of an adhesive layer and the base film is then peeled off together with the peeling layer. Next, the protective layer to which the optical or magneto-optical recording layer is adhered is adhesively attached to a card base in such a manner that the optical or magneto-optical recording layer is interposed therebetween whereby an optical or magneto-optical recording card is completely produced. The transfer type recording medium can be preserved in such a state that it is wound about a reel. Accordingly, the transfer type recording medium is adhered to the protective layer when the optical or magneto-optical recording card is produced, and thereafter it is adhered to the card base. Thus, the optical or magneto-optical recording card can be produced at a high productive efficiency.

摘要： The invention relates to a scheme for correctly reading data pits with a reader even if an optical recording card is fed slantwise.If the optical recording card is slanted relative to a line sensor for reading the card, the line sensor may ride on two or more data pit columns. However, discriminator pits are formed at the start and end of each data pit column so that the data can be processed after deciding if the optical recording card is disposed slantwise or not.A relatively short data pit column with discriminator pits formed at the start and end thereof is used. A plurality of data pit columns are disposed with a guide bar interposed therebetween. A readout signal from the discriminator pits is used for deciding if the data pit column has been read correctly, whereas a strobe signal read from the guide bar is used for initiating a memory selector.

摘要： A technique of optical card having high information recording density. In the optical cards, there are two types of optical cards having a read-only optical card and an additional recording optical card. Conventionally, separate readers for reproduction have been used due to difference in light reflectivity. In this invention, a light-absorbing layer (50) having light absorbing ability with respect to reading light (300) is arranged between a card side upon which the reading light is incident and a reflective surface of a pattern (21) of an optical data recording section (20), so that the optical cards have interchangeability therebetween in reading.
