Abstract

La présente invention concerne un appareil de production de support d'enregistrement pouvant former une couche d'enregistrement de la plus grande épaisseur possible (par exemple, 10 µm ou plus) dans une configuration simple. Un appareil de production de support d'enregistrement est caractérisé en ce qu'il est équipé d'un dispositif porteur qui porte sur ce dernier un matériau comprenant des fibres, comprenant des fibres de cellulose et un matériau hydrophobe et distribue le matériau comprenant des fibres à une première vitesse (V1), d'une unité de distribution qui distribue une base à une seconde vitesse (V2), et d'une unité de transfert qui transfère le matériau comprenant des fibres du dispositif porteur à la base, la direction de la distribution du matériau comprenant des fibres par le dispositif porteur et la direction de distribution de la base par l'unité de distribution étant parallèles l'une à l'autre dans l'unité de transfert et une relation représentée par la formule : (V1) > (V2) est satisfaite.
