Abstract
Un dispositif de stockage de données destiné à stocker des information numériques sous forme lisible est décrit, composé d'un ou plusieurs cléments de mémoire, chaque élément de mémoire comportant un conduit magnétique planaire capable de soutenir et de propager une paroi de domaine magnétique formée en une piste de propagation continue. Chaque piste continue est dotée d'au moins un et de préférence d'un grand nombre de n„uds d'inversion oé la direction de l'aimantation d'une paroi de domaine se propageant le long d'un conduit sous l'action d'un champ appliqué approprié, tel qu'un champ magnétique tournant, est changée.A data storage device for storing digital information in readable form is described, composed of one or more memory elements, each memory element comprising a planar magnetic conduit capable of supporting and propagating a magnetic domain wall formed in a continuous propagation track. Each continuous track is provided with at least one and preferably with a large number of reversing nodes in the direction of the magnetization of a domain wall propagating along a conduit under the action. of an appropriate applied field, such as a rotating magnetic field, is changed.
