  • Publication number: 20200339774
    Abstract: A protective window includes a flexible base film and a hard coating layer disposed on the flexible base film. The hard coating layer includes a silicone leveling agent and an inorganic antistatic agent. The coating layer includes an upper area and a lower area disposed between the upper area and the flexible base film, and a density of the inorganic antistatic agent in the lower area is greater than a density of the inorganic antistatic agent in the upper area.

  • Publication number: 20050259564
    Abstract: Disclosed herein is a super resolution optical disc. The super resolution optical disc comprises dielectric layers, and a mask layer formed between the dielectric layers, in which the mask layer is constructed as a complex mask layer comprising a metallic oxide (MOx) or metallic nitride (MNy), and a metallic thin film formed thereon. A size of the cavities and an amount of metallic particles in cavities created by illumination of recording laser can be controlled to increase a level of a reproduction signal for recording marks and to enhance the quality of the reproduction signal.

  • Publication number: 20050259563
    Abstract: Disclosed is a multi-layer super resolution optical disc. In the multi-layer super resolution optical disc, at least two recording layers, each of which comprises at least two mask layers and impact absorption layers formed between the mask layers, are laminated, and intermediate layers of polymer thermo-set by ultraviolet rays are formed between the recording layers. Accordingly, jitter characteristics for recording marks are improved, and recording density is enhanced.

  • Publication number: 20050170133
    Abstract: Disclosed is a super resolution optical disc. The super resolution optical disc comprises at least two mask layers. In one embodiment, the super resolution optical mask comprises a plurality of mask layers and impact absorption layers between the mask layers, and may further comprise diffusing prevention layers between the mask layer and the impact absorption layer. In another embodiment, the super resolution optical mask comprises a plurality of recording layers and dielectric layers separating the recording layers, each of the recording layers including two mask layers and an impact absorption layer between the mask layers or including two mask layers, an impact absorption layer between the mask layers, and diffusion preventing layers between the mask layer and the impact absorption layer. Accordingly, recording marks have an enhanced shape at an outer periphery of the marks, thereby enhancing the quality of the reproduction signal and enabling high-density multi-level recording.
