Abstract

"DISCO óPTICO DE ALTA DENSIDADE E MéTODO PARA REPRODUçãO E GRAVAçãO DE DADOS DO MESMO". Um disco óptico de alta densidade como um digital versatile disc de alta densidade (HD-DVD) ou Blu-ray disc, e um método para reproduzir ou gravar dados do disco óptico de alta densidade. O disco óptico de alta densidade inclui uma área de entrada, uma área de dados e uma área de saída. A área de entrada tem informações principais. Um comprimento mínimo de marca ou espaço das informações principais gravadas na área de entrada é mais longo do que aquele de dados gravados na área de dados. As informações principais da área de entrada são copiadas para a área de saída. Com base no método de reprodução ou gravação de dados, um dispositivo de disco óptico pode ler corretamente e confirmar as informações principais do disco óptico de alta densidade, minimizar a interferência entre uma marca e espaço em dados de gravação de alta densidade, reduzir os efeitos de arranhões ou poeira no disco, e evitar eficientemente uma operação errónea de reprodução ou gravação de dados.
