"We can state with absolute certainty that no computer in the world can access the data on this disc," said spokesman Brett Campbell. "We are also confident that no-one is going to be able to produce pirate copies in this format without going to a heck of a lot of trouble. This is without doubt the best anti-piracy invention the music industry has ever seen."

As part of the invention's rigorous testing process, the designers gave some discs to a group of teenage computer experts who regularly use file swapping software and who admit to pirating music CDs. Despite several days of trying, none of them were able to hack into the disc's code or access any of the music files contained within it.
