Abstract :
We performed a numerical simulation using a three-disk model with shrouds to evaluate the effect of air flows in the axial direction in a hard disk drive. And to clarify the relationships between disk surface pressure and disk flutter that have been a matter of conjecture, we performed a response analysis using the unsteady hydrodynamic force that was obtained as the excitation force by our numerical simulation.
