ABSTRACT:
An electrostatic discharge device for a flying height tester which measures the air gap of a recording head. The tester includes a transparent disk that is rotated by a spindle motor. The spindle motor is mounted to a spin stand. The tester has a manifold that is mounted to the spin stand and directs a flow of ionized fluid to a bottom surface of the disk. The manifold is also electrically grounded. The ionized fluid and electrically grounded manifold provide an electrical path that discharge electrostatic charge located on the bottom surface of the disk. The manifold extends from an inner disk diameter to an outer disk diameter so that ionized fluid is introduced to the entire bottom surface of the rotating disk. Additionally, the manifold location is such that the ionized fluid provides an electrical path from the disk to the manifold that is relatively constant across the surface of the disk. The manifold location insures that the electrostatic charge is discharged from the entire bottom surface of the disk. The manifold is also grounded by a fixed wire to provide a reliable ground path for the device.
