    • A protection member and an optical pickup device using the same are provided to protect an optical information recording medium and a lens by forming a protection member having an ultrahigh molecular weight polyethylene porous film. A protection member and an optical pickup device using the same comprise a lens and an ultrahigh molecular weight polyethylene porous film(2). The lens collects light on an optical information recording medium. The protection member comprises the ultrahigh molecular weight polyethylene porous film as a protection member for preventing contact(1) between optical information recording mediums optically recording or reproducing information from the optical information recording medium or on the optical information recording medium.
    • 提供一种保护构件和使用其的光学拾取装置,以通过形成具有超高分子量聚乙烯多孔膜的保护构件来保护光学信息记录介质和透镜。 保护构件和使用其的光学拾取装置包括透镜和超高分子量聚乙烯多孔膜(2)。 透镜将光收集在光学信息记录介质上。 保护构件包括超高分子量聚乙烯多孔膜作为保护构件,用于防止光学信息记录介质光学记录或再现来自光学信息记录介质的信息或光信息记录介质上的接触(1)。
