Abstract

Un disco de medio optico pregrabado de densidad de datos alta que tiene una densidad de datos de cuando menos 7.5 Gigabyts por capa de disco o 0.17Gigabyts por centímetro cuadrado (Gb/cm2) por capa y un grado de réplica tal que la profundidad de fosapromedio es igual a 1/4 hasta 1/8 veces (la longitud deonda del láser dividida entre el índice de refraccion del disco); o un disco de medio optico que se puede volver a escribir que tiene una densidad de datos decuando menos 0.05 Gb/cm2, en donde cuando menos 75% de réplica se logra como se mide por una combinacion de altura de estria y los ángulos de las paralelaslaterales izquierda y derecha, y en donde el disco pregrabado o que se puede volver a escribir tiene un retardo menor de 25 nm por0.6 milímetros de grosor desustrato, y una absorbencia de agua menor del 0.5% medido de acuerdo con ATSM D570.
