Abstract

L'invention concerne un appareil destiné à rendre un disque compact non lisible comprenant des premier et des second éléments de pressage et au moins un élément de destruction placés entre les éléments de pressage. Les éléments de pressage sont conçus de manière à les faire coïncider pour presser l'élément de destruction contre le disque placé entre ceux-ci, endommageant ainsi les informations se trouvant sur la surface support du disque. Dans un mode de réalisation préféré, le ou chaque élément de destruction comprend des grattoirs pouvant être dotés d'une lame dentée ou d'un matériau abrasif. La rotation du disque par rapport aux grattoirs lorsque le disque est placé entre les éléments de pressage résulte en ce la surface support du disque sur laquelle se trouvent les informations sont griffées ou autrement endommagées. L'invention concerne également un procédé destiné à rendre non lisible un disque compact.
