ABSTRACT:
The present invention provides a spindle motor shaft mechanically supporting via at least a bearing a hub of a spindle motor provided in a magnetic disc storage device for allowing the spindle motor to rotate around the spindle motor shaft. The spindle motor shaft comprises an aluminum-beryllium alloy which has such a high vibration attenuation factor as to effectively attenuate a vibration caused at the bearing in rotation of the spindle motor around the spindle motor shaft. As a result, the aluminum-beryllium alloy spindle motor shaft prevents transmission of the vibration through the spindle motor shaft to a cover of a housing. The noise caused by vibration of the cover member of the housing can be reduced.
