ABSTRACT:
A copy-protected compact disc and a method for producing the optical disc and preventing unauthorized copying is provided. In one embodiment, the contents of at least one of the lead-in items in the optical disc are altered so that it is no longer uniform, thereby making a copied disc effectively corrupted and unplayable.
