Abstract

MéTODO E DISPOSITIVO PARA GRAVAçãO óPTICA EM MEIO DE DISCO óPTICO. Apresente invenção refere-se a um método de gravação óptica para direção de um trem de pulsos de gravação para um meio de disco óptico a fim de formar marcas sobre o mesmo e para gravação de informação como informação a cerca das posições de borda das referidas marcas e dos espaços entre as marcas, o trem de pulsos de gravação tendo sido criado por meio de modulação de luz de laser em múltiplos níveis de potência. O método inclui: codificação de dados a serem gravados em dados codificados, consistindo na combinação de marcas, e espaços; classificação das referidas marcas dentro dos referidos dados codificados com base no comprimento de marca e nos comprimentos de espaços precedentes ou sucessivos das marcas; desvio da posição da segunda borda de pulso contato a partir da porção extrema do trem de pulsos de gravação para formação das referidas marcas,depedendo do resultado da referida classificação, para ajustar o referido trem de pulsos de gravação; e direção do referido trem de pulsos de gravação para o meio de disco óptico a fim de forma as referidas marcas sobre o mesmo.
