  • Patent number: 6861653
    Abstract: An equipment and method for inline infrared (IR) ultraviolet (UV) irradiation of recording media is disclosed. The components of the equipment include a saddle for holding a recording medium such as a disc, a conveyor that travels the saddle through a tunnel in which one or more IR and UV lamps are positioned to direct IR and UV light on the recording media traveling through the tunnel. The efficacy of the bonding of the lubricant to the recording medium by UV light is substantially enhanced by exposing the recording medium to IR light prior to exposure to UV light.
