Patent ID: 8521005

Claim:
A device for rendering a digital media unusable, wherein the media includes a volume descriptor that stores information allowing for use of the media, the device comprising: a frame; a first guide protruding from the frame, operable to engage an outer edge of the media; a second guide protruding from the frame at a distance of between 120 millimeters (mm) and 125 mm away from the first guide, operable to engage the outer edge of the media opposite the first guide, wherein the first guide and the second guide are positioned to constrain relative motion between the frame and the media in at least one dimension; one or more scraping elements coupled to the frame, wherein at least one of the one or more scraping elements is operable to damage a volume descriptor of the media when the frame is moved with the constrained motion relative to the media; and a pressure element coupled to at least one of the first guide and the second guide, wherein the pressure element is operable to maintain pressure on the media against at least one of the one or more scraping elements, and wherein the frame, the first guide, the second guide, and the pressure element forms a slot through which the media may pass.
