Abstract

El medio de grabación óptica tiene una capa de grabación (2) sensible para la grabación en una primera longitud de onda y sensible para la lectura en una segunda longitud de onda, la capa de grabación (2) tiene una estructura de surco (4), en donde en la primera longitud de onda, la estructura de surco (4) tiene una eficiencia de difracción en un primer orden de difracción suficientemente grande para generar una señal en contrafase, y en la segunda longitud de onda ésta tiene una eficiencia de difracción en un primer orden de difracción cerca del cero. La cabeza óptica lectora para grabar en un medio de grabación óptica está ideada para ser leída con una segunda longitud de onda y una segunda apertura numérica está caracterizada porque tiene una fuente luminosa para generar un haz luminoso en una primera longitud de onda y una apertura numérica dada por la segunda apertura numérica multiplicada con la proporción de la primera longitud de onda y la segunda longitud de onda.
