Abstract

L'invention concerne un procédé servant à configurer un disque dur et consistant à appliquer un traitement lithographique à une couche supérieure résistante du disque dur, ladite couche étant exposée à un faisceau composé de multiples petits faisceaux secondaires optiques ou électroniques. Les points focaux de ces faisceaux secondaires multiples sont, de préférence, situés à des distances radiales différentes d'un point central du disque dur et, dans un mode de réalisation préféré, sur une ligne s'étendant du point central du disque dur à un bord de celui-ci.
