Mechanical chip promises huge data storage

"A super-dense memory chip that stores data in the form of nanoscale holes in a plastic film has made its public debut at the CeBIT electronics exhibition in Hanover, Germany.

Storing data in the form of holes is not new - CDs use pits in a polycarbonate disc, for instance, and 19th-century looms stored patterns on punched cards. But the "Millipede" technology from IBM's Zurich lab promises very high capacity thanks to its use of holes just 10 nanometres wide. This means that a square chip measuring 2.4 centimetres on a side should be able to store 125 gigabytes, says the company, equivalent to 25 DVDs."
