Cover and security tag fixed directly to an optical discs

摘要

A cover of a plastics material is adhered to the operative surface of a CD or other optical disc to protect that disc surface. The cover is of substantially the same peripheral shape and size as the surface of the disc on which it is affixed. A security tag is adhered onto the outer surface of the cover and is thus held onto the surface of the disc. The security tag may be detectable by external means, for example, at the exit of a premises, whereby a warning is provided if there is an attempt to remove the disc from the premises. The cover may be removable so that both the cover and tag may be removed in order to play the disc.
