ABSTRACT:
A static eliminator comprises a contact mounted to a gimbal spring backed by a damping pad supported by a load spring. The contact bears against the polished end surface of the motor shaft of a disk drive so static electricity is grounded through the gimbal. The geometric arrangement of the contact and shaft is such as to prevent generation of vibration and excess noise as the spindle rotates.
