Abstract

Patente de Invenção para <B>"MEIO DE ARMAZENAMENTO óTICO DE CAMPO PRóXIMO E SISTEMA DE ARMAZENAMENTO DE DADOS óTICOS PARA O MESMO"<D>. Um sistema de armazenamento de dados óticos escreve ou lê informação com relação a um meio de armazenamento ótico usando uma captação ótica incluindo um sistema ótico de imersão de estado sólido ou lente de imersão de estado sólido para geração de campo próximo. O meio de armazenamento ótico inclui uma camada de registro que é posta em uma superfície que se opõe à outra superfície de uma camada transmissiva ótica que se opõe ao sistema ótica de imersão de estado sólido ou lente de imersão de estado sólidso. A espessura da camada transmissiva ótica é maior do que um comprimento de onda de luz usado. O intervalo entre as superfícies da lente de imersão de estado sólido ou do sistema ótico de imersão de estado sólido, é menor do que um comprimento de onde de luz usado. Desse modo, o feixe de luz refletido a partir do interior de uma folga de ar e do interior do meio de armazenamento entre a folga de ar e a camada de registro, não funciona como ruído com relação à luz refletida a partir da camada de registro. Também, desde que a espessura de uma camada protetora ou um substrato que é uma superfície externa do meio de armazenamento ótico pode ser aumentada, a informação pode ser escrita ou lida com relação ao meio de armazenamento ótico tendo poeira e avaria.
