Patent abstract
A method and apparatus for permanently rendering data recorded on an optical disc unreadable, comprising a slotted alignment plate and a scarifying component. A disc rests against the plate so that the slot traverses the disc. The scarifying component slides through the slot and contacts the disc surface, thus creating an optically disruptive groove across a surface layer of the optical disc. This disruptive groove can pass through the index and data region and prevents access to previous data and information stored on the disc.
