  • High-density optical recording media and method for making same
    Patent number: 7986611
    Abstract: The present disclosure provides a high-density optical storage medium which comprises a substrate structure having a thickness of 1.0 mm or more and including one or more information layers, a high-density information layer bonded via an adhesive spacer layer to the substrate structure, and a cover layer over the high-density information layer. The high-density information layer can be formed by transferring a reflective film to the substrate structure from a substrate formed of a material (such as polymethyl methacrylate) that does not bond well with the reflective film.

  • Method and apparatus for vacuum assisted venting
    Publication number: 20030102590
    Abstract: A method and apparatus for vacuum assisted venting of an injection mold. The apparatus includes a main body structured to be mounted around an outer circumference of the injection mold and configured to facilitate application of a vacuum pressure therein. The method and apparatus are particularly directed towards preventing the accumulation of residual material inside an injection mold and reducing the frequency of disassembly and cleaning required for the injection mold.
    Type: Application

  • Compact disc curing assembly line with deforming to a predetermined curvature prior to complete cure
    Patent number: 5932042
    Abstract: Automatic process control of the optical disc bonding process is achieved by tacking the adhesive and deforming the composite prior to final bonding. A separator chuck is used to maintain the separation of the disc halves through tack curing and a disc deforming jig is used during final bonding to compensate for any tendency of the disc halves to deform during the bonding operation.
