Abstract:
An optical card having visible data marked on a base layer and a substantially transparent optical data recording layer formed over the base layer. A protective layer is laminated over the optical data recording layer. The visible data marked on the base may be marked in an ink visible only at a nonvisual wavelength, such as infrared. A reader scans the visible data marked on the base layer, since the optical recording layer covering the base layer is substantially transparent.
Abstract:
A valuable ticket—on which ticketing data is magnetically recorded and which is printed for issuance-includes a base a heat-sensitive layer provided on one side of the base, a protective layer provided on the heat-sensitive layer and a magnetic recording layer provided on the other side of the base. A ticket printer for magnetically recording and printing ticketing data on ticket blanks for issuance includes ticket blank holder means for holding ticket blanks, each comprising a base, a heat-sensitive layer and a protective layer provided on one side of the base and a magnetic recording layer provided on the other side of the base, magnetic recording means for magnetically recording ticketing data the magnetic recording layers of the ticket blanks contained in the ticket blank holder means, and thermal printing means for thermally printing the ticketing data on the heat-sensitive layers of the magnetically recorded ticket blanks for issuance.
