L'esperada revolució dels discs durs: més capacitat en menys espai
Per una part, es redueixen els tamanys dels discs durs, i per l’altra gràcies a la tecnologia de gravació perpendicular dels bits -enlloc de vertical-, es permet multiplicar per 10 la seva capacitat augmentant la densitat, i no l’espai.

Discs Durs "mini"

TOSHIBA and Samsung have upped the ante in the “memory war” by announcing plans to begin mass production of the world’s smallest hard disk drives [0,85 inches - 2.16 centímetres de diàmetre]. (..) later this year, in a move that is expected to revolutionise electronic gadgets.

Mobile phones will be one of the first devices to make use of the of the new hard disk, which will allow about 1,200 MP3 tracks to be stored on a standard phone handset (4Gb), (..) mobile phones will challenge Apple’s iPod and other portable music players.

(..)

Digital cameras and video recorders are also prime targets for being remodeled to contain the new discs. Handheld games machines, PDAs and DVD players are all expected to follow as mass-production causes the price of hard disks to fall.

  • Grabació perpendicular

    Parece ser que la grabación perpendicular estará disponible dentro de poco. Hoy en día los discos duros se graban longitudinalmente. Pero conforme se junta más y más bits los campos magnéticos de cada bit interfiere con el que tiene al lado, debilitándolo y haciéndolo ilegible.

    Como solución a esto existe la grabación perpendicular, que al grabar los bits verticalmente no se interfieren entre ellos aumentando la densidad de la información hasta los 230 gbits por pulgada cuadrada.

    (..)

    Perpendicular recording was pioneered by the late 19th century work of Danish scientist Valdemar Poulsen, who demonstrated magnetic recording with his telegraphone.

    (..)

    As storage prices come down and data capacity increases, more portable devices are coming out with built-in hard drives, (..) Last month, Samsung unveiled its first i300 mobile, for instance, with a 3GB internal hard drive for storing MP3 tracks and images.

    (..)

    Hitachi said it would start using perpendicular recording in the next generation of its products, in 2007 (..)

    (..) 3.5inch drives could hold up to a terabyte of data. (..)

    Last year, Toshiba became the first major manufacturer to come out with a 1.8-inch drive holding up to 40GB, which is used in the iPod and other MP3 players.

    It also has a 2Gb 0.85-inch hard drive and its 4GB 0.85-inch drive is planned for mid-2005.

    Hitachi also announced earlier this year its "Mikey" hard drive. It says it is the smallest one-inch hard drive with the highest storage capacity, between 8-10GB.

    Hitachi expects to ship its first perpendicular recording product in 2005 on a 2.5-inch hard drive, used in notebook computers and handheld devices.
