Abstract

) Se provee un medio de informacion optica (20) para grabar, tal como un DVD-blue, y un método para fabricar tal medio (20) . La lectura y grabacion en el medio (20) se lleva a cabo por medio de un haz de radiacion concentrado (10) teniendo una longitud de onda de radiacion lambda y una apertura numérica NA. Dicho medio posee un sustrato (1), y una pila (2) de capas provista sobre el mismo. La pila (2) comprende al menos una primera pila de grabacion (3) y k capas transmisoras del haz de radiacion (4,5). Cada capa de transmision (4,5) tiene un índice de refraccion ni y un grosor promedio di mm y 1 L i L k y k l 2. El grosor dk de la capa k (5) es determinado por la formula simple que depende de los parámetros ni para i = 1....k y di para i = 1....k-1. Tal medio (20) posee una aberracion esférica de cero o sustancialmente cero en el punto focal, estando en la capa de grabacion de la primera pila de grabacion (3), de dicho haz de radiacion (10).
