Hydrodynamic bearing for use in a spindle motor includes a shaft, a bearing sleeve encompassing the shaft with a small radial clearance, a plurality of hydrodynamic pressure generating grooves formed on at least one of an outer surface of the shaft and an inner surface of the bearing sleeve, and a base-plate, flange or another frame element of the motor. The bearing sleeve is constructed as a single component with the frame element of the motor.
