Abstract

Le disque comporte un substrat transparent, de préférence en matière synthétique, tel que du plexiglas présentant une couche de vernis durcie par rayonnement dans laquelle est présente la piste d'information. La couche d'information utilisée contient un composé protonique réticulable par rayonnement qui est aprotonique après durcissement. De préférence, ladite couche de vernis contient un composé de polythiol, ainsi qu'un composé de polyène dans un rapport équivalent de 1 : 1. Application : stockage d'information.
