(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 ...
(PhysOrg.com) -- A tiny grid pattern has led materials scientists at the National Institute of Standards and Technology (NIST) and the Institute of Solid State Physics in Russia to an unexpected finding—the surprisingly ...
