Abstract
The present invention relates to a stamper (10) for optical disc manufacturing, having a stamper substrate (12), a substrate surface (14) comprising Ni and/or NiO, and a self-assembled monolayer (16) at least partly covering the substrate surface. The present invention further relates to manufacturing methods for stampers (10) and optical discs (22).
