This means you could store a substantial library of DVD quality movies on your smartphone!
=======================================
IBM says they have made a significant leap forward in the viability of "Racetrack memory," a new technology design which has the potential to exponentially increase computing power. This new tech could give devices the ability to store as much as 100 times more information than they do now, which would be accessed at far greater speeds while utilizing "much less" energy than today's designs. In the future, a single portable device might be able to hold as much memory as today's business-class servers and run on a single battery charge for weeks at a time.
Racetrack memory works by storing data as magnetic regions (also called domains), which would be transported along nanowire "racetracks." Instead of forcing a computer to seek out the data it needs, as traditional computing systems do, the information would automatically slide along the racetrack to where it could be used. The result: powerful and efficient computing.
The concept of storing bits of data in the region between two magnetic domains (the domain wall) has been around for nearly a half century. However, manipulating domain walls was an expensive and power-needy endeavor. The new finding published in the current issue of the journal Science shows how engineers at IBM's Racetrack Memory Project were able to precisely and efficiently control the placement of these magnetic domains within a racetrack system. By controlling electrical pulses along the track, researchers were able to move these domains at hundreds of miles per hour and then stop them precisely at the position needed, allowing massive amounts of stored data to be accessed in a billionth of a second.
