Abstract
A disc drive data storage system includes a hydrodynamic bearing 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. A hydrodynamic bearing interconnects the stationary member and the rotatable member. At least a portion of a surface of one or more of the hydrodynamic bearing components has a tilt-limiting layer formed thereon to restrict the tilting distance between the working surfaces in the disc drive data storage system.
