Abstract

"DISCO óTICO COM DOIS TIPOS DE PADRõES DE OSCILAçãO E MéTODO PARA A FABRICAçãO DO MESMO". A presente invenção refere-se a uma relação sinal/ruído (SIN) aperfeiçoada para gravar dados em sulcos de um disco ótico de modo que uma grande quantidade de informações possa ser gravada na faixa de freq³ência mais baixa possível. Um disco ótico usando padrões de oscilação para gravar diferentes informações tem um primeiro sulco tendo um primeiro padrão de oscilação no qual um período de oscilação tem uma extremidade que se eleva bruscamente e uma extremidade que cai gradativamente e um segundo sulco tem um segundo padrão de oscilação no qual um período de oscilação tem uma extremidade de elevação gradativa e uma extremidade que cai bruscamente. Cada um do primeiro e do segundo padrão de oscilação é representado por um primeiro fundamental e um segundo harmónico de uma serie de Fourier. A polaridade desse segundo harmónico, que é um harmónico par, do segundo padrão de oscilação é oposto à polaridade do primeiro padrão de oscilação. Um método para fabricar esse disco ótico também é provido.
