摘要

Polishing is the most important operation to get super-smooth surface in magnetic disc substrate manufacturing. The flatness error of the substrate surface, however, may be caused mainly by this operation. With respect to the production of aluminum disc substrate with NiP plated layer, the generating mechanism of flatness error in polishing operation has been analyzed based on contact mechanics and tribology in this paper. The measures to improve the flatness were also discussed.
