A method for manufacturing a disk drive head suspension having a plated load point dimple. A photoresist mask having an opening with load point-defining side walls and a load point diameter is formed over a planar portion of a spring metal member. Metal is plated onto the spring metal member in the opening to form a load point having the load point diameter on the planar portion of the spring metal member.

Various embodiments concern a DSA suspension of a disk drive. The DSA suspension comprises a support configured to attach to the disk drive, the support comprising a proximal portion, a distal portion, and a linkage portion therebetween. The DSA head suspension system further comprises at least one motor mounted on the support, each motor positioned between the proximal portion and the distal portion. The DSA suspension further comprises a damper attached to some or all of the proximal portion, the motor(s), the distal portion, and the linkage portion. The damper can be a single layer or multilayered. The damper can comprise viscoelastic material. The damper can be adhesive. The damper may only be attached to the support and the motors and not to other components of the DSA suspension.
