Abstract

L'invention se rapporte à la reproduction de disque support d'information à partir d'une matrice gravée. Le procédé suivant l'invention utilise pour la reproduction une matrice gravée par tout moyen, les pistes étant parfaitement centrées sur cette matrice par rapport à un centre de rotation. La matrice est posée dans une enceinte à vide sur un axe support susceptible de tourner et est enduite sur toute sa surface d'un matériau polymérisable ne comportant pas de bulles d'air et, qui n'adhère pas au matériau constituant la matrice. Un substrat préalablement percé en son centre, équilibré, et enduit d'un matériau auquel adhère le matériau polymérisable est placé sur l'axe support et maintenu à distance de la matrice. Le vide est effectué dans l'enceinte et le substrat est amené au contact de la matrice. Lorsque la polymérisation est terminée, en dehors ou dans l'enceinte, le substrat portant la résine moulée est aisément séparé de la matrice. Application à la reproduction de disques en relief, notamment à la reproduction de disques vidéo.
