ABSTRACT:
A novel head stack assembly is disclosed. The novel head stack assembly includes a stamped actuator arm and a head gimbal assembly attached to the stamped actuator arm. 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 actuator arm also includes two or three longitudinally spaced-apart stamped protrusions. The stamped protrusions are in contact with the trace suspension flex, and each stamped protrusion extends from the actuator arm side surface.
