Abstract :
A model to predict the shock response of a 1.8-inch hard disk drive (HDD) is developed and verified by experiment. The feasibility of modeling the air bearing as linear springs is investigated. Result shows that when the vibration of the arm-suspension is concerned, the air bearing between the disk and slider can be modeled by linear springs to speed up the simulation.
