An electron microscope would require splitting the disk to expose the bit surface (and probably require heavy metal staining as well), but a decent optical microscope might reveal the bits. The question then would be how to automate the scanning so you are not bent over the microscope all day counting bits.

I concur with ChayoteMu about the data being unrecovereable if the disc was erased,
But is that really the case? Remember, when you "blank" a hard drive (overwriting it with zero's), you can still recover the previous data by using a magnetic force microscope. Shouldn't a similar process be feasible on blanked CD's? I would assume that there are tiny indentations that remain from a previous burn of a given dimple that might be observable through electron microscopy. Is anyone aware of such research?
