Abstract

método de fabricação para meio ótico de gravação, meio ótico de gravação, dispositivo ótico de informação e método de reprodução de informação um objetivo da invenção é melhorar a qualidade de um servo sinal e de um sinal de reprodução. as espessuras no sentido do formato de uma camada de cobertura e da primeira a (n- 1)-ésima camadas intermediárias do meio ótico de gravação tendo índices de refração nr1, nr2, ... , e nrn são respectivamente tr1, tr2, ... , e trn na ordem a partir de uma superfície do meio ótico de gravação em que a luz é incidente, as espessuras tr1, tr2, • • • i e trn são convertidas nas espessuras t1, t2, ... , refração predeterminado e tn de camadas tendo um índice de "no" , o que torna uma quantidade divergente igual a uma quantidade divergente de um feixe de luz resultante das espessuras tr1, tr2, .. . , e trn, uma diferença dff entre a soma de uma espessura "ti" até uma espessura "tj", e a soma de uma espessura "tk" até uma espessura "tm" é regulada para 1 mi ou mais (onde i, j, k, e m são, cada um, qualquer inteiro positivo que satisfaça a i menor igual a j menor que k menor igual a m menor igual a n), e as espessuras t1, t2, ... , e tn são calculadas por produtos de uma função f(n) expressa pela fórmula (1) a seguir, e as espessuras tr1, tr2 , ... , e trn: f(n)=-1,088n3+6,1027n2-12,042n+9,1007 ... ( 1) na fórmula (1), n=nr1, nr2, ... , e nrn.
