Well, I think it may be the sound of console reading the discs. Other matter is the scratches in the discs\' surface. I wonder how the console would be able to make those physical damages, taking into account that the only part of the device which approaches to the disc, is the lens, and if the lens touches (and, of course, scratches the disc) it would be damaged for sure. So I wonder again how the hell are those scratches made by the consoles.
