'Millipede' Prototype Shown at CeBIT

neutron_p writes "It was a subject of much controversy for last 5 - 7 years, but it's finally got protyped. At CeBIT, IBM for the first time shows the prototype of "Millipede" - nanomechanical data storage device. Using revolutionary nanotechnology, scientists at the IBM Zurich R&D Lab, Switzerland, have made it to the millionths of a millimeter range, achieving data storage densities of more than one terabit per square inch, equivalent to storing the content of 25 DVDs on an area the size of a postage stamp. The principle of operation is comparable with the old punch cards, but now with structural dimensions in the nanometer scale and the ability to erase data and rewrite the medium."
