If the platter has 2" and something usefull surface radius, thats about .5·10⁶ tracks per platter side, which is even more than the number you said, so you are about right and I wasn't.
A 3 1/2 inch across drive with a 2 inch useful radius. Where do you buy your drives? I need some of those! Seriously, I'd say a desktop 3 1/2 inch drive only has about 1 inch of useful radius. There's dead space in the middle that is about 1 inch in diameter (1/2" radius) and at least an 1/4th of an inch dead at the edge between the chassis / air / unused platter edge. fyi: I don't have a dead / disassembled drive handy to actually measure so I'm going from memory.
