An experimental technique to predict the onset of aeroelastic #utter of an enclosed computer memory disk is presented. The aerodynamic pressure is modelled as the sum of dissipative and circulatory linear operators, which subsumes as a special case the pressure generated in a thin hydrodynamic "lm b

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'
