Abstract
A method corrects track misregistration attributable to out-of-plane motions of a rotating disk in a hard disk drive, and includes the steps of measuring a base plate-roll-bias angle between the rotating data storage disk and the head arm with a precision measuring device, and connecting the head arm and load beam at a roll-bias angle selected to minimize track misregistration attributable to the roll-bias. A number of connection arrangements and structures are presented in order to achieve the desired reduction in track misregistration.
