ABSTRACT:
A video disc master of glass, having a metal surface with microscopic apertures therein representing information, is coated with a photosensitive resist. The resist is uniformly exposed through the glass disc. The unexposed resist is removed. The resulting disc having surface irregularities can be used in a first process to produce "stampers" for embossing replicas and, in a second process, to produce a mold for casting replicas.
