An apparatus for manufacturing pre-formatted linear optical data storage media including an elongated linear polymer layer. The apparatus includes a drum mounted for rotation about a rotation axis, and the drum includes a circumferential outer surface having a predetermined pattern of protrusions for embossing at least one pattern of optically readable embossments in the elongated linear polymer layer as the layer is rolled on the drum. The apparatus also includes a thermal radiation source positioned adjacent the drum for heating the embossments of the elongated linear polymer layer prior to the layer being removed from the protrusions of the outer surface of the drum.
L'invention concerne un appareil de fabrication de supports de stockage de données optiques linéaires préformatés comprenant une couche polymère linéaire étirée. Ledit appareil comporte un tambour monté de manière à tourner autour d'un axe de rotation et ledit tambour comprend une surface externe circonférentielle à motif prédéterminé de protubérances afin de graver en relief au moins un motif de gravures lisibles optiquement dans la couche polymère linéaire étirée, à mesure que la couche est enroulée sur le tambour. Cet appareil englobe également une source de rayonnement thermique placée adjacente au tambour, en vue de chauffer les gravures de la couche polymère linéaire étirée, avant le retrait de ladite couche des protubérances de la surface externe du tambour.
