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?
