What the...?

Of course you cannot change the physical data on the CD. No one said you could. The problem is that the laser reading is imperfect, you know, what with all the wobbling and fluttering disc during play, the out of round condition of most CDs, the less than perfect transparency of the clear layer, not to mention the background scattered laser light. You do realize the photodetector is a cheap $1.00 piece of junk, don't you? It's a miracle the CDs play at all. The other thing, it's about the error detection and correction system. It sucks.
