Abstract
L'invention concerne une méthode pour la réalisation d'un porteur d'information en matière synthétique, notamment un disque vidéo, selon lequel un moule est muni d'une résine de moulage liquide sur laquelle est appliquée un substrat. Après durcissement, l'ensemble substrat couche de résine durcie est sortie du moule. Le substrat est courbé de façon sphérique et appliqué comme tel contre la quantité de résine de moulage appliquée au centre du moule. La résine est laminée sur la surface du moule à fond liquide circulaire tandis que le substrat est courbé. Après étalement de la résine sur le moule et application du substrat contre la couche de résine, cette dernière est durcie. La courbure du substrat est de préférence réalisée par suspension flexible d'un substrat plan au bord de ce dernier, après quoi une pression gazeuse différente est établie des deux côtés du substrat. L'invention est également relative à un dispositif pour la mise en oeuvre du susdit procédé. Application : enregistrement de signaux de télévision.
