This is very interesting, but I think the problems with optical storage will become greater with such a system. Just think about how much more data will be blocked by a speck of dust, or a scratch in the surface of the disc. I think it might be better to come up with some other way of storing data. Of course, all of the other methods have their shortcomings, too, so it will be a question of which virtues and vices are preferable. Anyway, it is very interesting.

Too many people seem to spend too much time reading between the lines for what is not there instead of paying attention to what is there.
