Racetrack memory: Swiss researchers have managed to develop a new type of 'Racetrack' memory that can make your hard-drive 100,000 times faster. 'Racetrack' memory has no moving parts and doesn't require power to run like Graphics and Ram.
How it works?
For this concept to be feasible, each bit of information must be clearly separated from the next so that the data can be read reliably. Kläui overcame this hurdle by using vortices to create magnetic walls between the bits. Using this solution on a 30 nm thick iron-nickel disk, Kläui and his colleagues recorded even higher reading speeds than expected. Their results were published online October 25, 2010, in the journal Physical Review Letters.
Scientists of the IBM Research Center in Zurich (which is developing a racetrack memory) are ready to work with Kläui to build a prototype for this importance discovery. A market-ready device could be available in as little as 5-7 years.
