Modern hard drive technology is reaching its limits. Engineers have increased data-storage capacities by reducing the widths of the narrow tracks of magnetic material that record data inside a hard drive. Narrowing these tracks has required a concordant reduction in the size of the magnetic write head—the device used to create them. However, it is physically difficult to reduce the size of write heads any further. Kim Keng Teo and co-workers at the A*STAR Data Storage Institute, Singapore, and the Niigata Institute of Technology, Japan, have recently performed an analysis that highlights the promise of an alternative approach, which may sidestep this problem completely. https://phys.org/news/2013-04-simply-pattern-hard-capacities.html General Physics Wed, 10 Apr 2013 08:24:28 EDT news284801052 (PhysOrg.com) -- The majority of today's hard disks use perpendicular recording, which means their storage densities are limited to a few hundred gigabytes per square inch. Scientists have for some time been trying to find ways of increasing the limit, and a new method has been proposed that could stretch the limit as high as ten terabits (Tb) per square inch. https://phys.org/news/2010-05-hard-terabits-sq-inch.html Optics & Photonics Mon, 10 May 2010 07:40:01 EDT news192693274
