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.
