Abrégé
(EN)
An optical disc comprises an active disc in which information is recorded and a dummy disc for protecting the active disc, wherein the active disc and the dummy disc are bonded to form a single body, wherein the dummy disc is made of methylmethacrylate-acry-lonitrile-butadiene-styrene copolymer (MABS) resin.
(FR)
L'invention concerne un disque optique comprenant un disque actif dans lequel des informations sont enregistrées et un disque de leurre destiné à protéger le disque actif. Le disque actif et le disque de leurre sont collés pour former un corps monobloc. Le disque de leurre est constitué d'une résine copolymère de méthylméthacrylate-acrylonitrile-butadiène-styrène (MABS).
