Abstract

L'invention proposée porte sur la production de supports d'enregistrement magnétique. Elle consiste pour l'essentiel à appliquer sur une base un revêtement magnétique à gros grains, et à faire de sa couche en subsurface une couche magnétique à grains fins en exposant des segments du revêtement à gros grains à un rayonnement à laser pulsé nanoseconde répondant à certains paramètres.
