Abstract

L'invention concerne une structure d'enregistrement magnétique et son procédé de formation. La structure comprend un substrat 1 et un élément d'enregistrement magnétique stratifié 2 disposé sur au moins une partie de la surface exterieure du substrat et comprenant une couche magnétique 3, une couche colorée 5 et une couche de métal non magnétique 4 formée par dépôt sous vide et disposée entre la couche magnétique et la couche colorée, la couche magnétique étant plus près du substrat que la couche colorée. Il est ainsi possible de produire une structure d'enregistrement magnétique dont on a revêtu la surface d'une belle couleur sans pour autant altérer ses caractéristiques magnétiques.
