Abstract

"MEIO DE GRAVAçãO óTICO, PROCESSO DE FABRICAçãO DE MEIO DE GRAVAçãO óTICO, APARELHO PARA FABRICAçãO DE MEIO DE GRAVAçãO óTICO, PROGRAMA, E MEIO". Há muitos casos em que uma precisão é baixa para ler a informação única que identifica um indivíduo originária de um disco ótico que compreende uma pluralidade de camadas de informação. O disco ótico, de acordo com a presente invenção, é um disco ótico que compreende uma primeira camada de informação 102 e uma segunda camada de informação 104 para deter a informação, de modo que, por meio de luz incidente, (1) a informação venha a ser reproduzida ou (2) a informação venha a ser gravada e reproduzida, e que compreende uma área de interrupção de explosão que é formada na primeira camada de informação 102 e na qual é gravada a informação de identificação de indivíduo 106 unicamente fornecida ao disco ótico.
