Another from New Scientist:
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.
[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.
Apparently, some are questioning the need for a mechanical version of technology already available in other mediums.
