According to google and other sources. Thus total microns is quite a large number.

How many bits or bytes do I have the potential for? > You have 6.45 * 10^8 u^2 / inch^2 Your spot is 100 x 100 u = 10^4 u^2 So you get 6.45 * 10^4 spots / in^2 Each spot is 24 bits or 3 Bytes. So you get just under 200 kBytes / in^2 That would be an appallingly low density, even if you could do it. The problems involved in reading the color quickly, cheaply, and consistently would not be trivial.
