The recording head in a hard disk drive (HDD) is supported by an actuator assembly which is being controlled by a servo system. Structural resonance modes in the actuator impact the performance of the servo system. The actuator rocking mode has been identified as a major contributor to seek settling
As the recording track density increases in hard-disk drives, the off-track error-rejection capability of the servo controller must also be increased. The high rejection capability is achieved by increasing the servo bandwidth; however, the ability to extend the bandwidth is limited by the actuator'
As the track density of hard disk drives increases, further improvement in the performance of the read/write head positioning servo system is required. However, the servo performance is limited mainly by the inherent mechanical resonances of the head actuator. Passive damping has the potential to im
