Abstract

"MEIO DE INFORMAçãO óPTICO, E, PROCESSO PARA FABRICAR O MESMO". é provido um meio de informação óptico (20) para gravação, tal como DVR-azul, e um processo para fabricar tal meio (20). A leitura e gravação sobre o meio (20) é efetuada por meio de um feixe de radiação focalizado (10) possuindo um comprimento de onda de radiação <sym> e uma abertura numérica NA. Citado meio possui um substrato (1) e uma pilha (2) de camadas providas sobre ele. A pilha (2) compreende pelo menos uma primeira pilha de gravação (3) e k camadas transmissivas de feixe de radiação (4,5). Cada camada transmissiva (4,5) possui um índice de refração n~ i~ e uma espessura média d~ i~ <109>m e 1 = i = k e k = 2. A espessura d~ k~ da camada k (5) é determinada por uma fórmula simples que depende dos parâmetros n~ i~ para i = 1... k e d~ i~ para i= 1... k -1. Tal meio (20) possui aberração esférica zero ou substancialmente zero no ponto focal, estando na camada de gravação da primeira pilha de gravação (3) do citado feixe de radiação (10).
