Abstract

La présente invention concerne un formateur permettant d'inscrire des marques sur un support optique translucide tridimensionnel, de façon à permettre l'enregistrement et la lecture d'information sur le support. Ce formateur comprend un mécanisme de blocage permettant de maintenir le support, et au moins une unité optique étalonnée pour focaliser au moins un point limité de diffraction à l'intérieure du support à la profondeur correspondante. Une source de lumière au moins est optimisée pour l'inscription de marques, un bras déplaçant le point par rapport au support.
