Non-insect Millipedes

Here's some info on the staggering IBM Miilipede chip which they are currently developing:

Millipede is a non-volatile computer memory stored on nanoscopic pits burned into the surface of a thin polymer layer, read and written by a MEMS-based probe. It promises a data density of more than 1 Terabit per square inch (1 Gigabit per square millimeter), about four times the density of the best magnetic storage available today.

Millipede storage technology is being pursued as a potential replacement for magnetic recording in hard drives, at the same time reducing the form-factor to that of Flash media. IBM demoed a prototype millipede storage device at CeBIT 2005, and is trying to make the technology commercially available by 2007. At launch, it will probably be costlier, on a per-megabyte basis, than other prevalent technologies, but the disadvantage will be offset by the storage capacity that Millipede technology would offer.

It gets even cooler as time marches on.
