Abstract

PROCESSO DE ESCRITA ADAPTATIVO PARA APARELHAGEM DE REGISTRO óTICO DE ALTA DENSIDADE E CIRCUITO PARA O MESMO. São fornecidos processo de escrita adaptativo para aparelhagem de registro ótico de alta-densidade e um circuito para o mesmo. O circuito inclui um discriminador para a discriminação da magnitude da marca presente do dado de entrada e das magnitudes dos espaços de trilha e/ou principal, um gerador para controlar a forma de onda do pulso de escrita de acordo com a magnitude da marca presente do dado de entrada e das magnitudes dos espaços de trilha e/ou principal para a geração de um pulso de escrita adaptativo, e um driver para o acionamento da fonte luminosa através da conversão do pulso de escrita adaptativo em um sinal de corrente de acordo com os níveis de potência de acionamento para os canais respectivos. As larguras do primeiro e/ou último pulsos de uma forma de onda de pulso de escrita são variadas de acordo com a magnitude da marca presente do dado de entrada NRZI e da magnitude dos espaços de trilha e/ou principal, minimizando assim a instabilidade para acentuar a confiabilidade e desempenho do sistema.
