Abstract

a. Support d'enregistrement en forme de disque-modèle pour l'enregistrement optique, support formé d'une plaque de base transparente, essentiellement plane ayant une première et une seconde surfaces opposées, et une couche de matière photosensible appliquée sur première surface pour être exposée par un faisceau de lumière modulé par le signal à enregistrer. b. Support caractérisé en ce que la seconde surface est anti-réfléchissante.
