Abstract

"MEIO DE GRAVAçãO óPTICA E PROCESSO DE GRAVAçãO DE DADOS". é provido um novo meio de gravação capaz de obter alta densidade, confiabilidade em uma operação de gravação/reprodução e facilitar o processo que é realizado por um aparelho de execução. Uma quantidade de amplitude de oscilação de uma trilha é feita para ser 10 nm e 15 nm e um passo de trilha da trilha é feito 0,74Ám a 0,82Ám. Os valores determinados permitem que grande capacidade de gravação seja realizada e seja evitada a deterioração do desempenho da gravação/reprodução. Como informação de administração, é gravada a informação recomendada para uma operação de gravação/reprodução em uma posição periférica mais interna e uma posição periférica mais externa. O tamanho dos dados em uma seção de ligação torna-se o mesmo que o do setor para constituir o bloco de dados.
