发明名称 Refinement of spindle motor bearing gap
摘要 A method and system is provided for achieving good dynamic performance and negligible wear to spindle motor components. In an aspect, a disc drive storage system is provided having a hydro bearing surface coating for meeting bearing gap tolerance design specifications. In an aspect, the surface coating is a non-reactive coating of diamond like carbon (DLC), applied with physical vapor deposition (PVD). In an aspect, the surface coating nullifies any taper of an opposing surface coating. In an aspect, the hydro bearing, with an applied coating, defines a uniform gap between 0.5 microns and 6 microns.
