Abstract

Se proporciona un medio de grabación de información con tres o más capas de grabación de información. Cuando la potencia de reproducción de un haz de láser requerido para reproducir la información a partir de una capa de grabación de información L(n) es expresada como (Pw(n)), y la potencia de reproducción de un haz de láser requerido para reproducir la información -de una capa de grabación de información L(n+a) es expresada como (Pw(n-+-a)), el espesor de material de base entre las capas de grabación de información es un espesor en donde la intensidad de luz obtenida cuando la capa de grabación de información (L(n+a)) es irradiada con un haz de láser que tiene la potencia de reproducción (Pw(n)) es equivalente o más baja que la intensidad de luz obtenida cuando la capa de grabación de información (L(n+a)) es irradiada con un haz de láser que tiene la potencia de reproducción (Pw(n+a)).
