Abstract
Un portador de registro que contiene información en una estructura de información ópticamente legible, reflectante de la radiación, que comprende áreas o zonas de información, las cuales están dispuestas en pistas de información, que están separadas entre sí en la dirección de las pistas por áreas intermedias, y que tienen una profundidad de fase que es sensiblemente constante en todo el portador de registro, caracterizado porque la sección transversal a la dirección de la pista, de las áreas de información, es sensiblemente en forma de V, porque la profundidad de fase de las áreas de información tiene un valor comprendido ente 100º y 125º, y porque el ángulo de inclinación entre las paredes de las áreas de información y la normal al portador de registro es sensiblemente constante y tiene un valor comprendido entre 65º y 85º.
