Design considerations for reducing shock responses of a micro-drive

Based on the operational shock simulation of the head disk assembly (HDA) of a micro-drive, we proposed three possible approaches for reducing the shock responses. These approaches are, 1) to change the Young´s modulus, 2) to change the thickness of the hinge, and 3) to change the boundary condition of the disk. Numerical results show that the third approach with a clamped boundary condition for the disk produces the most significant effect on reducing the shock responses.
