Production process and production line for manufacturing multilayer optical discs are proposed. The technology allows producing of multilayer optical reflective discs of any format CD ROM, DVD ROM, Blue Ray, HD-DVD, DVD-R, DVD- RW, etc., and particularly Versatile Multilayer Disc (VMD) using mostly existing CD/DVD production lines with reasonable upgrading. L'invention concerne un procédé de production et une ligne de production destinés à fabriquer des disques optiques multicouches. La technologie permet de produire des disques réfléchissants optiques multicouches de n'importe quel format CD ROM, DVD ROM, Blue Ray, HD-DVD, DVD-R, DVD- RW, etc., et, en particulier, un Disque Multicouche Versatile (VMD), utilisant principalement des lignes de production CD/DVD existantes avec une mise à niveau raisonnable.
