Abstract

Se describe un medio optico de almacenamiento de informacion de multiples apilamientos (15) para la grabacion y lectura por medio de un haz enfocado de radiacion de (10). El haz penetra en el medio (15) a traves de una primera cara de entrada (11), y tiene al menos un primer substrato (1) por lo menos con un lado del mismo: un primer apilamiento de capa (2), que comprende una primera capa de informacion, un segundo apilamiento de capa (4), que comprende una segunda capa de informacion. El segundo apilamiento de capa esta presente en una posicion mas cerca de la primera cara de entrada (11) que al primer apilamiento de capa (2) y se encuentra separado del primer apilamiento de capa por medio de una primera capa transparente espaciadora (3). Cada una del primer y segundo apilamientos de capa tiene una reflexion efectiva del haz de radiacion Re si estuviera entre 0.04 y 0.08 de acuerdo con la especificacion del estandar del Disco de Rayo Azul (BD). Un tercer apilamiento de capa (6), que comprende una tercera capa de informacion, esta presente en una posicion mas cerca de la primera cara de entrada (11) y se encuentra separada del segundo apilamiento de capa (4) por medio de una segunda capa transparente espaciadora (5). El tercer apilamiento de capa tiene una transmision del haz de radiacion T3 mas grande que 0.70, y la tercera capa de informacion es una capa solo de lectura o una capa de una escritura. Es conseguido el medio optico de almacenamiento de datos de multiples apilamientos, el cual tiene un aumento den la capacidad de datos y tiene valores de reflexion compatibles con la especificacion del estandar BD de doble apilamiento.
