In one aspect, a fluid dynamic bearing system is provided. The system may include a first member and a second member disposed for relative rotation about an axis of rotation and having opposing substantially planar surfaces defining an axial gap. A bearing region is disposed circumferentially around the axis of rotation and a relatively large gap region is disposed circumferentially around the bearing region, the large gap region having an average gap distance greater than the bearing region. The large gap region further includes at least one support pad forming a localized narrow gap distance in the axial gap to provide support between the opposed surfaces at a radial distance greater than the bearing region. For example, the support pad may support the surfaces against an externally applied force or moment that may tilt one member relative to the other.
