This paper presents a theoretical study on the shock response of a contact recording head when a half-sine acceleration impulse is applied to the head-disk assembly system. The contact head is modeled by a cantilever beam with a concentrated mass at the tip. The surface undulation and the vibration of disk are both taken into account in the analysis. The contact force between the head and the disk is assumed to follow the Hertz theory. The head jumping height and the contact force between the head and the disk are studied in detail. The obtained results show that the maximum jumping height and contact force are significantly dependent on the amplitude and duration of the applied impulsive disturbance.
