Magnetspeicher der neusten Generation sind 100 000 mal schneller als herkömmliche Festplatten

Das Paul Scherrer Institut verstärkt seine Zusammenarbeit mit der ETH Lausanne

(PresseBox) (Villigen PSI, )
Computer-Festplatten könnten bald ausgedient haben: Forscher des Paul Scherrer Instituts PSI und der Universität Konstanz haben neuartige Magnetbänder untersucht und gezeigt, dass sie nicht nur sehr hohe Speicherdichten, sondern auch viel schnellere Zugriffszeiten als heutige Speichermedien zulassen. Diese so genannten Racetrack-Speicher ermöglichen die Produktion stossfester Datenspeicher, die herkömmliche Festplatten künftig ablösen könnten. Leiter der Studie war Mathias Kläui, der am 1. April eine von der ETH Lausanne und dem PSI gemeinsam finanzierte Professur antritt.

Racetrack-Speicher kodieren die Information in Form von magnetischen Bits. Diese Informationseinheiten sind wie bei alten Magnetbändern (z.B. Videokassetten) hintereinander auf einem Draht abgelegt. Anders als bei
