Abstract

Se describe un medio de grabación de información óptico en forma de disco (115). Está provisto con un substrato (101), primera a n capas de información (102-104) (en donde n es un entero de 3 o más) que son laminadas sobre el substrato, k capas intermedias (105, 106) (k=1, 2 hasta n-1), que son provistas entre la k capa de información y la (k+1) capa de información, y una capa protectora (107) que está provista sobre la n capa de información. El ancho de variación en espesor desde la superficie de capa protectora (107a) hasta las capas de información (102-104) respectivas es ± 3 µm o menos con respecto al valor medio de este espesor en la región con un radio de 23 mm a 24 mm desde el centro del medio de grabación de información óptico.
