Abstract

Se describe un medio de grabación de información que comprende N número (N es un entero que satisface N = 3) de capas de información sobre las cuales puede grabarse información, y que permite que la información sea grabada en cada una de las capas de información y permite que la información grabada en cada una de las capas de información sea reproducida al ser irradiado con luz láser. El N número de capas de información incluye una N capa de información, una (N-1) capa de información, una (N-2) capa de información, una segunda capa de información y una primera capa de información ubicada secuencialmente desde un lado de incidencia de luz láser. Una reflectancia de la N capa de información es RN, y una reflectancia de la M capa de información (M se refiere a cada entero que satisface N > M = 1) es RM. La luz usada para irradiar la N capa de información para reproducir información grabada en la N capa de información tiene una potencia de reproducción de límite superior PrNmax, y la luz láser usada para irradiar la M capa de información para reproducir información grabada en la M capa de información tiene una potencia de reproducción de límite superior PrMmax. Se satisfacen concurrentemente las siguientes expresiones (1) y (2): RN > RM (1), PrNmax < PrMmax. (2).
