A good question that had me searching through magazines to find the
article where I read about it. It was in "New Scientist" 31 July.
It says "can store". Re-reading the article it seems it may not be
holographic but it uses "..a red laser with a wavelentgh of 79 nm
in a way that controls the shape and spacing of individual bits,
providing clear spacing between them. It is then read using UV light
from a helium-neon laser..". How much data they've *actually* stored
in the device is not mentioned.
