Abstract

La présente invention concerne une couche de revêtement magnétique souple (16) sur laquelle un chemin magnétique pour faire circuler le flux magnétique d'une tête magnétique à nouveau vers la tête est formé, une couche intermédiaire non magnétique (22) comme couche de commande d'orientation cristalline et une couche d'enregistrement (24) comme couche magnétique sont formées de manière séquentielle sur un substrat non magnétique (12), la direction facile de magnétisation étant perpendiculaire à la surface de film de la couche d'enregistrement (24), la couche d'enregistrement (24) piège une paroi de domaine et comprend un site de butée de paroi de domaine (25) formé par des ions d'irradiation et une région définie par le site de butée de paroi de domaine (25) sert de bit d'enregistrement. Dans un tel support d'enregistrement magnétique vertical (10), la couche d'enregistrement (24) a des surfaces régulières (24a, 24b) perpendiculaires à la direction de laminage du support d'enregistrement magnétique vertical (10) dans une partie où est formé le site de butée de paroi de domaine (25), et une couche de protection d'ion (18), pour empêcher une implantation d'ion de la couche intermédiaire non magnétique (22) à la couche de revêtement magnétique souple (16), est fournie entre la couche intermédiaire non magnétique (22) et la couche de revêtement magnétique souple (16).
