A method of forming a hydrodynamic bearing surface on a workpiece is
provided. The method comprises electrochemically etching away all
material in a region of the surface, except for portions of the region
defined by a land pattern on an etching cathode. The step of removing
forms a continuous recessed region comprising grooves formed between the
portions of the region defined by the land pattern, and a relief cut
region circumscribing the workpiece.
