Abstract

MÉTODOS PARA FIXAR UM VALOR àTIMO DE UM PARÂMETRO DE ESCRITA PARA USO EM UM APARELHO DE GRAVAÇçO àPTICA E PARA FIXAR UM VALOR àTIMO DE UM NÍVEL DE POTÊNCIA DE ESCRITA DE UM FEIXE DE RADIAÇçO, APARELHO DE GRAVAÇçO àPTICA, E, MEIO DE GRAVAÇçO àPTICA. A invenção relaciona-se a um método para fixar um valor ótimo de um parâmetro de escrita para uso em um aparelho de gravação óptica para escrever informação sobre um meio de gravação óptica por meio de um feixe de radiação. O valor ótimo de um parâmetro de escrita é achado derivando uma pluralidade de níveis de potência de escrita caracteristicos (P~ char~) de uma pluralidade de funções de ajuste de curva. Cada nível de potência de escrita característico (P~ char~) tem um valor inicial associado do nível de potência de escrita (TV), e o valor ótimo do parâmetro de escrita é achado comparando a níveis de potência de escrita característicos aos níveis de potência de escrita iniciais. A invenção também relaciona-se a um aparelho de gravação óptica para gravar informação sobre um meio de gravação óptica, o aparelho tendo uma fonte de radiação para emitir um feixe de radiação tendo um valor controlável de um nível de potência de escrita para gravar informação sobre o meio de gravação. Adicionalmente, a invenção relaciona-se a um meio de gravação óptica para gravar informação irradiando o meio de gravação por meio de um feixe de radiação.
