Abstract

Un portador de registro como se describe, que tiene capas de alta densidad y regulares de informacion. La capa (2) de densidad regular, e.g. en un formato CD regular, está colocada en el fondo del substrato, y se lee a través del substrato con un rayo láser. El grosor del substrato está dentro de la especificacion del CD, e.g. 1.2 mm. Por lo menos una capa (3) de alta densidad está formada por un material que es (cercanamente) transparente para una longitud de onda láser de los reproductores CD regulares (X - 780 nm), pero es (por lo menos parcialmente) reflector para longitudes de onda más cortas usadas para discos de alta densidad (X - 635 nm). Para alcanzar una alta densidad, se usan fondos más pequeños a inclinaciones de pista más pequeños en la (s) capa(s) capa(s) de alta densidad. Para alcanzar un objetivo de rastreo pequeño, la capa de alta densidad es colocada más cerca del lado de la entrada del rayo láser en el substrato. Esto permite una apertura numérica más alta del lente de enfoque, y por lo tanto, un objetivo más pequeño. La capa de alta densidad es colocada preferiblemente a la mitad del substrato, e.g. a 0.6 mm, porque en ese caso la configuracion de la capa de alta densidad será compatible con los discos de dos lados de alta densidad que tienen un grosor total de 1.2 mm. El contenido de informacion de la capa regular puede ser duplicado en la capa de alta densidad, o se puede representar por un esquema diferente de codificacion.
