Abstract

"MEIO DE DISCO óPTICO; APARELHO DE DISCO óPTICO E MéTODO PARA REPRODUçãO DE MEIO DE DISCO óPTICO". Um meio de disco óptico compara uma ranhura de trilha, junto à qual estão gravadas as informações principais. A ranhura de trilha está dividida em uma pluralidade de blocos. Cada pluralidade de blocos inclui uma pluralidade de estruturas. Cada pluralidade de estruturas inclui uma forma de wobbles indicando sub-informações, entre a pluralidade de formas prescritas. Cada pluralidade de blocos tem informações de endereços. As informações de endereços são representadas por uma seq³ência de, pelo menos, uma peça de sub-informações representada pela forma de wobbles de, pelo menos, uma das pluralidades de estruturas.
