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
This work aims to develop a method for predicting the displacement and failure of the Head Actuator Assembly (HAA) during a drop test. When a Hard Disk Drive (HDD) is dropped from a certain height, it will accelerate due to gravity until it hits the ground with a certain speed, and the head suspensi
