Abstract

"SUPORTE PARA GRAVAçãO óPTICA, APARELHO PARAVARRER UM SUPORTE DE GRAVAçãO óPTICA E PROCESSODE FABRICAçãO DE UM SUPORTE DE GRAVAçãO". Umsuporte de gravação é descrito que compreende uma trilha parasuportar dados codificados em marcações ópticas. Um parâmetroda trilha tem uma variação periódica para gerar um sinal variável aovarrer a trilha, por exemplo uma variação do centro de umapré-ranhura usualmente designado de "oscilação".A trilhaadicionalmente compreende elementos de referência, p.ex.cabeçalhos, interrompendo a variação periódica. A fase davariação periódica após os elementos de referência é indicativa deuma propriedade do suporte de gravação para controlar avarredura do suporte de gravação na dependência da ditapropriedade. Particularmente a fase pode indicar se ou não o fundoda pré-ranhura está mais próximo do lado de entrada do feixe devarredura do disco. Outrossim um dispositivo de varredura édescrito compreendendo um detector para detectar a fasebaseado sobre o sinal variável. O aparelho adapta seu dispositivosde controle de varredura à propriedade indicada.
