The head gimbal assembly includes a trace suspension flex having a metal base layer and a plurality of conductors supported by the metal base layer. The stamped actuator arm includes an actuator arm side surface that extends longitudinally along the stamped actuator arm.

The stamped protrusions are in contact with the trace suspension flex, and each stamped protrusion extends from the actuator arm side surface.
