发明名称 Integrated-lead suspension vibration-canceling member
摘要 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.
