ABSTRACT:
An optical recording medium includes an optical recording layer readable by radiation within a first wavelength band, and first and second visible information layers. The first information region is overlaid by the optical recording layer. An opaque layer is provided between the first and second information layers. The optical recording layer has a transmissivity for visible radiation so that the first visible information is visually readable through the optical recording layer.
