Vibration control with thin-film-coil actuator for head-positioning system in hard disk drives

In a head-positioning system of hard disk drives, various mechanical resonances may degrade performance or stability of the control system. In these mechanical resonances, a torsional mode of a head-stack assembly (HSA), in which a resonant frequency is between 3 kHz and 4 kHz, has a large negative...
