An actuator arm assembly of a hard disk drive. The assembly includes a
flexure that is attached to an actuator arm and a head coupled to the
flexure. 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.
