Abstract
L'invention concerne un support d'enregistrement de l'information comprenant un substrat ayant une surface réfléchissant la lumière, et une couche d'un matériau absorbant la lumière recouvrant la surface réfléchissant la lumière; l'épaisseur de la couche absorbant la lumière est telle qu'elle établisse une condition d'anti-réflexion de la lumière à une fréquence donnée. Selon l'invention, une couche d'un matériau transparent 17 est placée entre la surface réfléchissante 15 et la couche de matériau absorbant la lumière 19, l'épaisseur de la couche 17 étant égale à un multiple entier de la moitié de la longueur d'onde de la lumière à la fréquence donnée dans le matériau transparent. L'invention s'applique notamment à l'enregistrement de vidéodisques.
