  • Patent number: 8921011
    Abstract: A method is provided for mastering optically variable devices (OVDs) used to authenticate optical discs. The method generally includes the steps of providing a laser beam recorder (LBR), introducing a substrate to the LBR, and exposing a portion of the substrate to the LBR. The mastering system thus includes the LBR, which has a laser that emits a beam, a processor or computer for programming or otherwise controlling the beam in order to expose the substrate and create the desired optical effect. Depending on the material used for the substrate, the exposure is then developed, if necessary, and processed to generate a master for the OVD. The OVD can then be replicated in order to provide authentic resultant products or articles, such as optical discs.

  • Patent number: 5533002
    Abstract: An optical data storage disc, for example, a compact disc, has one side formed with a pattern of indentations defining a digital data recording, and this side is metallized and further coated with a layer, which is embossed with a relief pattern defining a holographic image. The hologram may extend across the whole surface of the disc and is visible from the top side of the disc, while digital information is readable in a conventional manner using a laser directed at the underside of the disc.

  • Patent number: 5452282
    Abstract: A process for producing an optical data storage disc (e.g., a compact disc) carrying a digital recording and also carries a holographic image is disclosed. The holographic recording occupies an area (14) separate from the area (12) occupied by the digital recording, for example, the holographic recording may be positioned in an annular area encircling the central area occupied by the digital recording.
