Abstract
A conductive lock washer for safely dissipating electrostatic charge which builds up on a disk surface without discharge across the head/dish gap. The lock washer, including a series of alternating inner and outer tabs, acts to reduce torque on the spindle washer damper and hoop stress on the washer itself, while still creating a conductive pathway to the top cover of the hard drive assembly.
