Abstract

Cette piste de données est formée par une bande de pellicule magnétique isotropique et destinée à un système de memoire à parois à traverses. La bande de pellicule magnétique isotropique, définissant la piste de données, utilise l'anisotropie induite par sa forme pour maintenir la paroi à traverses à l'intérieur du contour de la bande de pellicule. L'utilisation de l'anisotropie induite par la forme d'une bande isotropique de pellicule magnétique permet l'emploi de pistes de données courbes.
