An apparatus, system, and method are disclosed for compensating for
high-gain vibration modes resulting from asymmetrical traces in
integrated lead suspensions in hard disk drives. A compensation member
secures to an actuated arm opposite a mount plate securing a head gimbal
assembly (HGA) to the arm. The compensation member includes an elastic
portion primarily mirroring the elastic properties of asymmetrical
elastic properties of conductive traces extending along the HGA and arm.
The elastic portion secures to an inertial portion primarily mirroring
inertial properties, such as center of mass and moment of inertia, of the
HGA. The elastic portion may be formed as a strip of material attached at
its end points to the inertial portion. The inertial portion may be
formed as a flat plate secured to the actuated arm in a manner similar to
the mount plate.
