For instance, about ten years ago we started to see things that looked like compact disks, but they weren't written quite like compact disks. They didn't follow the standard. We called them 'corrupt disks', and the idea of them was that they would play in an audio player, but it was impossible to read them on a computer. These different methods had various problems.
