Title (EN) MANUFACTURING METHOD AND MANUFACTURING APPARATUS FOR AN OPTICAL DATA RECORDING MEDIUM, AND AN OPTICAL DATA RECORDING MEDIUM
(FR) PROCEDE ET APPAREIL DE FABRICATION D'UN SUPPORT D'ENREGISTREMENT DE DONNEES OPTIQUES, ET SUPPORT D'ENREGISTREMENT DE DONNEES OPTIQUES
Abstract:
(EN) A manufacturing method for an optical data recording medium having a substrate with at least one signal recording layer and a resin layer for passing light, the manufacturing method includes: coating a radiation-curable resin on the substrate; and forming the resin layer by curing at least a part of the radiation-curable resin by increasing the rotational speed of the substrate to a first speed, then decreasing the rotational speed of the substrate, and emitting radiation while the rotational speed of the substrate is decreasing.
(FR) L'invention concerne un procédé de fabrication d'un support d'enregistrement de données optiques, qui comprend un substrat présentant au moins une couche d'enregistrement de signaux et une couche de résine laissant passer la lumière. Le procédé de fabrication consiste à: déposer une résine polymérisable par rayonnement sur le substrat; et former la couche de résine par polymérisation d'au moins une partie de la résine polymérisable par rayonnement, en augmentant la vitesse de rotation du substrat selon une première vitesse, puis en diminuant la vitesse de rotation du substrat et en émettant un rayonnement pendant cette baisse de la vitesse de rotation du substrat.
