Therefore this does not sound too promising when applied in miniaturized non-laboratory equipement. Its basically a cool idea, since one can read a holograhpic crystal using all sorts of different wavelengths which would allow to reuse the same data position in the crystal multiple times. That makes it basically like a multilayer optical data disk (e.g. blue ray) but in 3D, so instead of an area of for example 1024x1024 bits you have a space of 1024x1024x1024 bits available (if we consider the medium size such a way that along its length 1024 bits can be transscribed). But as I said before, it is hard (today) to bring such crystals into a state where it can be read and written (meta stable). If there only was a meta stable optical material that worked under normal conditions and is highly rewritable and translucent.
