This seems like the same stuff I've seen at
trinket stores in Hong Kong where they have
artwork etched in a block of acrylic by a
laser.

Subject: OT: 1,000GB sugarcube
"A group of researchers at Japan's Kyoto University and Central Glass
Company have developed a 'memory cube', a sugarcube-sized piece of glass
used as optical storage. The system works using femtosecond lasers to
produce tiny bubbles within the glass. These laser produced extremely short
bursts of light. The glass contains the element samarium and the resulting
bubbles become luminous, enabling them to be read again. The bubbles are 400
nanometers in diameter and placed 100 nanometers apart. A cube with 2,000
layers has been produced capable of storing 1,000GB of data.
The technology has reportedly reached the point when development can begin
on a possible commercial version. The possibilities for mass storage are
incredible, complete libraries you can lose behind the back of the sofa! It
remains to be seen if the extensive technology used can be made commercially
viable."
The first disc drive I ever saw had a massive capacity of 120MB and was
fitted to a HP3000 Series III. Don't remember the model number but think
they were referred to as 'wash tubs' because a) they were that size and
shape, and b) the disc pack could be removed via a flap in the top. Wonder
how many of these "sugarcube's" would fit in a casing that size?
As a deceased relative of mine used to say "How about the size of them
apples!!!!"
