Abstract
A fluid dynamic bearing system having pressure-generating surface patterns that comprises at least two bearing parts that are rotatable with respect to one another and form a bearing gap filled with bearing fluid between associated bearing surfaces. The surface patterns are disposed on at least one bearing surface that is defined by a first rim and a second rim, hydrodynamic pressure being built up within the bearing gap on rotation of the bearing parts with respect to one another. At least parts of the surface patterns extend from the first rim to the second rim of the bearing surface.
