Abstract

"PROCESSO E APARELHO GRAVADOR PARA GRAVAR INFORMAçõES OPTICAMENTE GRAVáVEIS". O pedido refere-se a um processo de e a um aparelho para gravar informações sobre um suporte de informações óptico em multicamadas (1). Em um sistema de gravação óptica, as informações podem ser gravadas sobre uma camada selecionada (41) de um suporte em multicamadas (1) focalizando o feixe laser (2) sobre a camada selecionada. As camadas intermediárias (42) interagem com o feixe laser (2). Uma propriedade importante na gravação de informações sobre um suporte em multicamadas (1) é o coeficiente de transmissão destas camadas intermediárias (42). O coeficiente de transmissão depende das propriedades físicas da camada intermediária (42) e do fato ou não das informações terem sido gravadas. O aparelho inclui um circuito (55) que deriva informações (711) acerca das alterações dos coeficientes de transmissão das camadas (41a 43 quando informações são gravadas sobre estas camadas. Na base desta informação (711) um circuito determina a seq³ência na qual as camadas (41 a 43) devem ser gravadas. A seq³ência pode ser selecionada de modo a minimizar a intensidade do feixe laser (2), dessa maneira prevenindo o aquecimento desnecessário do suporte (1) e permitindo a utilização de fontes de feixe laser (3) comparativamente simples e de baixo custo.
