An actuator arm assembly for a disk drive includes first and second
stamped actuator arms including first and second arm portions, first and
second body portions defining first and second body surfaces, and first
and second coil-supporting arm portions defining first and second pairs
of coil supporting arms for supporting a coil portion of a voice coil
motor. When the first and second stamped actuator arms are attached to
one another, the first pair of coil supporting arms faces and is in
contact with the second pair of coil supporting arms to define first and
second coil attachment surfaces, and the first body surface faces and is
in contact with the second body surface to define a third coil attachment
surface.
