Abstract
A method of forming a patterned lapping plate by providing a working tool having a pattern comprising a plurality of raised teeth, each of the raised teeth having a base, at least one side wall, and a terminal end, and patterning the lapping plate with the tool to provide a working surface having an inverse pattern of the tool surface in the working surface of the lapping plate, the patterning process plastically deforming the working surface of the lapping plate.
