Security device for destroying the information bearing layer and data of a compact disc

A device for removing the information bearing surface and the data carried thereby from the substrate layer of a compact disc while maintaining the integrity and identification of the substrate layer, said device comprising:

• a housing defining a central cavity, said housing including a first portion defining a first cavity chamber, a second portion having an interior surface and selectively attachable to said first portion to enclose said interior surface within said cavity chamber, said interior surface being sized and shaped to engage a compact disc, and a third portion defining a second cavity chamber contiguous with said first chamber;
• means for selectively mounting a compact disc within said first chamber;
• means disposed within said first chamber for physically removing the information bearing surface of a compact disc positioned on said mounting means by reducing it to particulate material;
• means for biasing said physical removal means against the information bearing surface of a compact disc positioned on said mounting means as said information bearing surface is reduced to particulate material;
• means disposed in said second chamber for reducing the size of said particulate material to 250 microns or less;
• and
• means for actuating said physical removal means.

A device for the complete declassification of compact discs by the removal of information bearing layers therefrom, said device comprising:

• a first housing portion defining a first central cavity therewithin and having open first and second ends;
• a second housing portion including an interior surface sized and shaped to engage a compact disc, said second housing portion being removably securable across the open first end of said first housing portion for selectively covering said open first end to enclose said interior surface within said first central cavity;
• a third housing portion operatively secured to the open second end of said first housing portion and defining a second central cavity contiguous with said first central cavity;
• means for selectively mounting a compact disc within said first central cavity;
• means disposed within said first central cavity for physically removing the information bearing layer in the form of particulate material from the substrate layer of a compact disc mounted within said first central cavity;
• means for continuously biasing said removal means against the information bearing layer of a compact disc mounted within said first central cavity until said information bearing layer is converted to particulate material;
• and
• means for actuating said removal means.

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 housing including a first portion having an inner surface defining a first chamber, and a second portion selectively securable to said first portion to enclose said first chamber;
• a mounting element for selectively securing a compact disc within said chamber;
• an abrading assembly disposed within said chamber for removing the information bearing surface from the substrate layer of a compact disc positioned on said mounting means by physically converting said information bearing surface to particulate material;
• a mechanism for biasing said abrading assembly against the information bearing surface of a compact disc positioned on said mounting means as said information bearing surface is reduced to particulate material;
• and
• an agent for actuating said abrading assembly.

• a grinding member disposed in said second chamber for reducing the size of said particulate material to less than 250 microns;
• and
• an agent for actuating said abrading assembly.
