The head is coupled to a pre-amplifier circuit of the drive. The head is also electrically grounded through the flexure and the actuator arm. To improve the reliability of the ground path the flexure has a spring that is contact with a slot of the actuator arm. The spring provides a ground path from the head to the actuator arm.
