ABSTRACT:
An embodiment of the present invention is a process in which a polymer solution is spin coated onto a master data recording disk, such as glass substrate with photoresist images, before separating. After drying and forming polymer, a polymer membrane results which is a faithful reproduction of micron-sized optical recording features on the surface of the master. Such membrane is either peeled-off and mounted to a pellicle-like frame or first laminated to a stiffer, stronger substrate before peeling to support the duplicate.
