At CeBit, IBM showed off a prototype storage technology which can hold the equivalent of 25 DVDs on an area the size of a postage stamp.
Millipede packs a punch
At CeBit, IBM showed off a prototype storage technology called Millipede. Big Blue says the MEMS (micro-electrical-mechanical system) device can hold far more data per square inch than can magnetic systems.
The Millipede prototype uses a two-dimensional array of silicon probes, or cantilevers, and a micro-mechanical scanner, which moves the storage medium relative to the array. For reading, writing and erasing of data, the cantilever tips are brought into contact with the storage medium.
