Improve non-repetitive runout (NRRO) associated with the system's structural dynamics and operating vibrations. [Solution] A data storage device such as a hard disk drive (HDD) includes a rotary pivot bearing assembly of a rotary actuator configured with a bearing span smaller than the maximum available bearing span, thereby reducing the rotary pivot tilt (PT) gain of the corresponding acoustic transfer function relative to the rotational pivot tilt (PT) gain of the original acoustic transfer function corresponding to the maximum available bearing span. To counteract the resulting decrease in coil torsion and rotational pivot tilt frequency, the voice coil is thickened vertically to increase the coil torsion (CT) frequency and rotational pivot tilt frequency, bringing them closer to their values ​​in the original acoustic transfer function. Combining a relatively short bearing span with a relatively thick voice coil ensures and improves performance by maintaining relatively high CT and PT frequencies while guaranteeing a relatively low PT gain.
