  • Publication number: 20070210467
    Abstract: An apparatus for fabricating a coverlayer of optical information storage media is disclosed. The apparatus comprises a rotating platform, a rotating plate and a UV irradiation system. A substrate is disposed on the rotating platform and a radiation setting resin material is disposed on a surface of the substrate. The rotating plate is moved towards the rotating platform to compress the radiation-setting resin material against the substrate. The resulting structure is rotated by rotating the rotating platform. A thin radiation-setting resin layer with a uniform thickness is formed on the substrate. The radiation-setting resin layer is illuminated by a UV light to harden the radiation-setting resin layer. Next, the rotating plate is separated from the radiation-setting resin layer while the radiation-setting resin layer remains adhered to the substrate. The hardened radiation-setting resin layer serves as a coverlayer of the optical information storage media.
