Abstract

Se da una descripcion de un sistema de almacenamiento optico que comprende un medio de almacenamiento optico y un dispositivo con cabeza optica. El medio tiene un substrato, una memoria de retencion temporal de registro y una memoria de retencion temporal con recubrimiento protector transparente opticamente, para proteger la memoria de retencion temporal de registro del impacto por el dispositivo con cabeza optica. La memoria de retencion temporal con recubrimiento protector comprende una capa multiple de al menos: una primera capa con un espesor menor que 40 nm y una superficie con una energia superficial menor que 1.5 J/m2, y una segunda capa, adyacente a la primera capa, con un modulo de Young E menor que 10 GPa y mayor que 0.001 GPa. Esta combinacion de capas es muy resistente al dano causado por el impacto mecanico del dispositivo de cabeza optica. No se requiere lubricantes.
