Abstract
Methods and apparatus for forming microstructures in the surface of polymeric web materials for use as optical memory substrates. The microstructures may be formed by laminating a hot stamper to a web of material with a selective time/temperature profile. The stamper may be heated to melt flow the surface of the web and stabilize before separation. The stamper may be carried by a support that is independent of the press. The web of polymeric material may be provided with a flow enhancer to improve image formation. Also described herein are methods and apparatus for making optical memory modules, such as disks, which include novel stampers, coating applicators, and finishing systems.
