Abstract

L'invention concerne le domaine de l'enregistrement vidéo. Le disque d'enregistrement vidéo comporte deux groupes de pistes alternés (q, s pour le premier groupe et q, r pour le second). Sur ces pistes, une cavité représente un bit 1, l'absence de cavité un bit 0. La profondeur des cavités des pistes q, s et celle d2 des pistes p, r sont reliées aux longueurs d'onde lambda1 et lambda2 des lumières utilisées pour lire chaque groupe de pistes de telle sorte que, lorsqu'une piste est lue, la lumière réfléchie par les pistes adjacentes soit la même, que les pistes adjacentes contiennent une cavité ou pas. Applicable notamment à l'enregistrement et à la reproduction de programmes de télévision.
