"ALGORITHMS: Aiming at terabit disk media"

Perpendicular recording techniques promise to more than double density capabilities in the next few years, increasing from the 200 Gbits/square inch that longitudinal recording techniques pack today to as high as 500 Gbits/square inch. Fujitsu Laboratories Ltd. proposes that to double density again, to the terabit per square inch domain, researchers add nanoscale patterns to preformat the location of bit cells in perpendicular media. This is a capability it demonstrated recently in cooperation with nearby Kanagawa Academy of Science and Technology (Japan).
