This paper presents a study of the transient response of HDA subjected to a half-sine shock pulse in the axial and pitching directions. The solution is obtained using the multi-model expansion approximation and applying the Galerkin method of the resulting equations. Numerical results are obtained using the Newmark βmethod for a 3.5'' hard disk-head system. It is found that the relative distance between the disk and the head becomes maximum when the input duration γ is about 1.5 times the natural half-period of the fundamental (0,0) mode. Results also show that the air film stiffness between the head and the disk should be high in order to realize a shock-proof head.
