Abstract

UNIDADE PARA ACESSAR UM PORTADOR DE REGISTRO óPTICO, MéTODO PARA DETERMINAR O TIPO DE PORTADOR DE REGISTRO óPTICO, E, PROGRAMA DE COMPUTADOR A presente invenção refere-se a um dispositivo para acessar um portador de registro óptico (2) compreendendo meios (4) para determinar o tipo de portador de registro, em particular para diferenciar um portador de registro somente de leitura de um portador de registro gravável ou capaz de ser escrito novamente tendo um sulco de vibração na zona de entrada, tais meios compreendendo: uma unidade de medição de DPD (41) para medir o sinal diferencial de detecção de fase, uma unidade de medição de PP (42) para medir o sinal simétrico (PP) no caso em que nenhum sinal de DPD puder ser medido, uma unidade de travamento de vibração para travar, no caso em que um sinal de PP puder ser medido, na vibração inerente ao sulco de vibração mencionado usando um primeiro e/ou um segundo ajuste de polaridade, e uma unidade de indicação (44) para gerar um primeiro sinal de indicação mostrando que o portador de registro é um portador de registro somente de leitura se um sinal de DPD puder ser medido e que o portador de registro é um portador de registro gravável ou capaz de ser escrito novamente se nenhum sinal de DPD mas um sinal de PP puder ser medido e se o travamento na vibração foi bem sucedido. Em uma incorporação adicional, um segundo sinal de indicação é gerado mostrando o tipo de polaridade no caso de um portador de registro gravável ou capaz de ser escrito novamente.
