However, you must remember that when the smaller the radious, less information you can record. In a CD, the fisrt 3" can carry much less data than the other 2".

I don't feel like doing the math now, I don't recall all the formulas I learned in the Analith Geometry (or whatever it's called there in US (I'm brazilian)), but I dare to say that 180MB is a reasonable amount of data that a 3" CD can save.
