Title:
METHOD AND APPARATUS FOR PRODUCING OPTICAL RECORDING MEDIA WITH ACCURATELY PARALLEL SURFACES
Document Type and Number:
WIPO Patent Application WO2002093571
Kind Code:
A3
Abstract:
An apparatus and method that produces recording media using at least two platens (16, 18). A first platen (16) is movable relative to a second platen(18), and each platen has respective first and second support surfaces onto which substrates (12, 14) are placed, the first and second substrates each having inner and outer longitudinal surfaces. A centering device (19) aligns the respective substrates relative to a one or more reference positions, a positioning system (32) provides a degree of parallelism between the outer longitudinal surfaces of each of the substrates (12, 14) and produces a desired gap between the inner longitudinal surfaces of the substrates(12, 14) , and a dispensing unit which emits a liquid medium within the gap between inner longitudinal surfaces of the substrates.
