This paper presents an approach to design a suspension assembly for high density HDDs by using topology optimization as well as a subsequent shape optimization. The design starts from a very simple initial draft, and the design objectives are defined to minimize the spring rate and maximize the resonant frequencies of the 1^<st> bending, 1^<st> torsion and sway modes of the suspension. An optimal design concept can be generated from the topology optimization. Then the design is further tuned by using the shape optimization, and finally, an optimal design of the suspension assembly for femto sliders is presented with much better dynamic characteristics.
