  • Method and apparatus for producing optical recording media with accurately parallel surfaces
    Patent number: 6881464
    Abstract: An apparatus and method that produces recording media using at least two platens. A first platen is movable relative to a second platen, and each platen has respective first and second support surfaces onto which substrates are placed, the first and second substrates each having inner and outer longitudinal surfaces. A centering device aligns the respective substrates relative to a one or more reference positions, a positioning system provides a degree of parallelism between the outer longitudinal surfaces of each of the substrates and produces a desired gap between the inner longitudinal surfaces of the substrates, and a dispensing unit which emits a liquid medium within the gap between inner longitudinal surfaces of the substrates.
    Type: Grant
    Filed: May 14, 2002
    Date of Patent: April 19, 2005
    Assignee: Aprilis, Inc.
