Abstract

"CAMADA DE GRAVAçãO PARA MEIO DE GRAVAçãO DE INFORMAçãO óPTICA E ALVO DE SUBLIMAçãO CATóDICA PARA O MESMO". Proporciona-se uma camada de gravação para meio de gravação de informação óptica que não é somente excelente na refletividade inicial, criação de marcas de gravação, e assemelhados, mas também excelente em durabilidade sob um ambiente de alta temperatura e alta umidade; e que pode ser adequadamente aplicado a um disco óptico de geração seguinte que utiliza um feixe de laser violeta azul. A camada de gravação para o meio de gravação de informação óptica usada para criar marcas de gravação por irradiação de um feixe de laser compreende uma liga à base de Sn que contém de 5 a 10 por cento atómicos de In e/ou 12 a 40 por cento atómicos de Zn.
