Abstract
Perfeccionamientos en un portador de registro en el cual se almacena información en una estructura de información reflectante de la radiación que es legible con un haz de radiación óptica y que comprende áreas de información dispuestas en el sentido de la pista las cuales, en la dirección de la pista y transversalmente a la dirección de la pista, están espaciadas entre sí por áreas intermedias, estando las superficies de las áreas de información dispuestas sustancialmente en un primer plano, las superficies de las áreas intermedias sustancialmente en un segundo plano y siendo la distancia entre el primer plano y el segundo plano sustancialmente constante sobre todo el portador de registro, caracterizados porque el ángulo de inclinación entre las paredes de las áreas de información y una perpendicular al portador de registro tiene un valor comprendido entre 30º y 65º, y porque la distancia geométrica entre el primer plano y el segundo plano tiene un valor comprendido entre 165/N y 270/N nanometros, siendo N el índice de refracción de un medio transparente que está dispuesto entre el primer plano y el segundo plano.
