Abstract

L'invention concerne une mémoire à domaines cylindriques. Cette mémoire à domaines cylindriques comporte un milieu de mémorisation comportant des domaines cylindriques, une structure de déplacement constituée par plusieurs éléments individuels en forme de L 1 disposés en étant étagés les uns par rapport aux autres et constituant des boucles de mémoire 2, les domaines cylindriques étant déplacés sous l'action d'un champ tournant magnétique le long dune voie déterminée par la structure de déplacement. Application notamment aux mémoires à circulation de l'information.
