Abstract
Apparatus for rendering a compact disc unplayable comprises first and second pressing elements and at least one spoiling element interposed between the pressing elements. The pressing elements are adapted to be brought together to press the spoiling element against a disc placed therebetween thus causing damage to the information bearing surface of the disc. In a preferred embodiment, the or each spoiling element includes scraping means which may comprise a serrated blade or an abrasive material. Rotation of the disc relative to the scraping means when the disc is sandwiched between the pressing elements results in the disc's information bearing surface being scratched or otherwise damaged. A method of rendering unplayable a compact disc is also described.
