Estimating the term…
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.
A device for removing the information bearing surface and the data carried thereby from the substrate layer of a compact disc, said device comprising:
A field portable device for the complete declassification of compact discs by the removal of information bearing layers therefrom, said device comprising:
In a device for the destruction of information layers of a compact disc to prevent the recovery of exploitable information therefrom including a housing for containing the compact discs to be destroyed and means for physically destroying the information layers thereof, the improvement wherein said device further comprises an upper housing member defining a central cavity therewithin having an open lower end, a lower housing member including an interior surface sized and shaped to carry a compact disc, said lower housing member being removably attachable to said upper housing member for selectively covering said open lower end to enclose said interior surface within said cavity, a plurality of rotatable head assemblies disposed within said cavity each including a plurality of grinding elements mounted thereon for bias against the information baring layer of a compact disc mounted onto said interior surface, resilient means for biasing said grinding elements against the information bearing layer of a compact disc positioned on said interior surface until said information bearing layer is entirely removed, and means for actuating said head assemblies and grinding elements.
