Abstract
A system for defacing compact discs so as destroy information stored thereon includes a defacer unit and a feed unit for feeding discs one at a time, with vertical orientation, to the defacer unit. A falling vertically-oriented disc is caught and held between two sets of driven endless rubber belts which transport the disc between opposed knurling wheels which embed grooves in opposite sides of the disc substrate without, however, cracking the substrate. The knurling wheels are designed to give the grooves an identifiable pattern.
