I'm thinking that it used two 166GB platters, numbers don't add up otherwise. scaling from the 2platter 320GB to the 1platter version exceeds what one would expect from a 33% increase in platter density, plus isn't linear density only increased only in a logarithmic fashion? EG: it takes a 4fold increase in density to get a two fold increase in per line density. Or am I wrong? does anyone know if the number of tracks(for lack of a better term) are maintained constant, or do they go up with the rest of the disc such that the track increase is proportionate to the linear density increase?
