A pivot cartridge assembly with improved resonance characteristics. One end of the pivot bearing shaft is mounted to the base of the disc drive, and the other end is secured to the cover of the disc drive in such a manner that the resonance characteristics of the pivot bearing assembly is improved in both the axial and radial direction of the pivot bearing shaft.

Damper design on pivot bearing shaft by vibration reduction

An apparatus for isolating vibration in pivot bearing assemblies that is incorporated in a standard pivot bearing assembly without requiring modification of the pivot bearing assembly. Washers are used between the pivot bearing assembly and the base plate of a disc drive upon which the assembly is mounted. In addition, a second washer is positioned on the shaft of the assembly and is held in place by a shoulder screw which fastens the assembly to the base plate.
