    摘要： An optical storage medium is disclosed that includes an optical disc having layers of graphene on one or both sides of the disc to provide wear protection against scratches and mechanical abrasion. Grahpene is a hard material that is 97.7% optically transparent. Thus, layers of graphene at or near the exterior sides of an optical disc provide wear protection to the optical media from mechanical abrasion and scratches while allowing laser light to pass through the graphene layers to read or write to the optical media.

    摘要： A description is given of an optical storage system comprising an optical storage medium (1) and an optical head device (6). The medium has a substrate (2), a recording stack (3) and an optically transparent protective coating stack (4 and 5), for protecting the recording stack from impact by the optical head device (6). The protective coating stack comprises a multi-layer (4 and 5) of at least: a first layer (5) with a thickness smaller than 40 nm and a surface with a surface energy smaller than 1.5 J/m2, and a second layer (4), adjacent the first layer (5), with a Young's modulus E smaller than 10 GPa and larger than 0.001 GPa. This combination of layers (4 and 5) is very resistant to damage caused by mechanical impact of the optical head device (6). No lubricants are required.

    摘要： Constructed is an optical recording medium which is so formed as to have excellent surface flatness and with respect to which information is recorded or reproduced with the use of a near-field optical system. The optical recording medium is one which performs at least one of recording and reproduction of information by irradiation of light. The optical recording medium has a substrate 1 which has fine concavities and convexities 2 formed on the surface on a side where irradiation of light is performed, and a formed film layer having at least a recording layer and having a fine concavities and convexities surface reflecting the fine concavities and convexities 2 in itself. The optical recording medium also has a light transmission flattenable film 4 which is so formed on the formed film layer as to have the fine concavities and convexities surface buried therein, and the surface of which is polished and which has a single-layer or a multi-layer structure having a hardness enabling the film to be polished, has a transmission characteristic with respect to the irradiated light to thereby permits transmission of a light irradiated with respect to this optical recording medium.
