Abstract: The contact model of lapping and polishing for magnetic disk
substrate is presented. Based on elastic contact theory.
Pressure distribution for this model are analyzed. Further, the
effects of various parameters ,such as the material properties
of the PVA (polyvinyl acetate), grinding stone, the polishing pad
and the base plate, the thickness of the pad or the stone on the
pressure distribution have been discussed.
Key words: Lapping Polishing Magnetic disk substrate
