Abstract :
Finite element model of the head disk assembly (HDA) of a small-form factor drive was created. Operational shock simulation and modal analysis were conducted with this model. The pulse width effect of a half-sine acceleration pulse on the shock responses was investigated. Three possible approaches were suggested for reducing the shock responses.
