ABSTRACT:
A head stack assembly (HSA) is disclosed for use in a disk drive comprising a disk, wherein a merge tool is used to merge the HSA with the disk. The HSA comprises at least one actuator arm with a suspension connected to the distal end of the actuator arm. A multi-level shipping comb attached to the actuator arm comprises a finger having a first surface and a second, raised surface. During shipping of the HSA, the first surface of the finger contacts the suspension to protect against overstressing. During manufacture of the disk drive, the shipping comb is actuated so that the second surface contacts the suspension thereby bending the suspension in a vertical direction to facilitate the insertion of the merge tool.
