  • Patent number: 6039637
    Abstract: A device is disclosed for removing the information bearing surface and the data carried thereby from the substrate layer of a compact disc. The device includes a housing which has a first portion having an inner surface defining a first chamber. A second housing portion is selectively securable to the first housing portion to enclose the first chamber. A mechanism is provided for selectively mounting a compact disc within the first chamber. An apparatus is disposed within the chamber for removing the information bearing surface from the substrate layer of a compact disc positioned on the mounting mechanism by physically converting the information bearing surface to particulate material. The removal apparatus is biased against the information-bearing surface of a compact disc positioned on the mounting mechanism as the information-bearing surface is reduced to particulate material. Finally, a mechanism is provided for selectively actuating the physical removal apparatus within the first chamber.

  • Patent number: 5954569
    Abstract: A device is disclosed for removing the information bearing surface and the data carried thereby from the substrate layer of a compact disc. The device includes a housing having an upper portion defining a top surface and a central cavity and a lower portion having interior and exterior surfaces. The lower portion is selectively attachable to the upper portion to enclose the lower portion interior surface within the cavity, the interior surface being sized and shaped for selectively carrying a compact disc. A mechanism is disposed within the cavity for physically removing the information bearing surface of a compact disc positioned on the lower portion interior surface. A member is provided for continuously biasing the physical removal mechanism against the information bearing surface of a compact disc positioned on the interior surface as the information bearing surface is being removed. Finally, an element is provided for actuating the physical removal mechanism.
