Beschreibung
Zusammenfassung:	A disc drive storage system including a housing having a central axis, a stationary member that is fixed with respect to the housing and coaxial with the central axis, and a rotatable member that is rotatable about the central axis with respect to the stationary member is described. A hydrodynamic bearing interconnects the stationary member and the rotatable member and includes at least one working surface comprising a wear resistant coating. Cette invention concerne un système de stockage/entraînement de disque comportant un boîtier à axe central, un élément stationnaire par rapport au boîtier et coaxial par rapport à l'axe central, et un élément rotatif tournant sur l'axe central par rapport à l'élément fixe. Un élément hydrodynamique relie l'élément fixe à l'élément rotatif et comprend au moins une surface de travail à revêtement résistant à l'usure.
