  Technology Review: A New Way to Read Hard Disks 

  http://www.technologyreview.com/Infotech/19364/?a=f

  Tuesday, September 11, 2007 A New Way to Read Hard Disks Researchers believe that the magneto-electric effect might be key to creating the sensors needed for ultra-high-capacity memory. By Prachi Patel-Predd ... Packing data: Hard disks will soon pack as much as one terabit of data per square inch--five times what disks carry now. Current reading devices will not be able to read the tiny bits, so researchers at the U.K.'s National Physical Laboratory have proposed a design for a new type of read-head sensor that might work. Credit: University of St. Andrews Data density on hard disks has roughly doubled every year for the past 30 years, and to keep up, researchers have made smaller and smaller sensors to read the tiny bits stored on a disk. Today's hard disks pack a mind-boggling amount of data--more than 200 gigabits in a square inch. But as the industry gears up for densities of up to one terabit per square inch, the sensors are reaching their physical limits. Researchers at the Na   [More...] [Less...]
