ROLL-BIASED HEAD SUSPENSION FOR REDUCED TRACK MISREGISTRATION

摘要

A method corrects track misregistraton attributable to out of plane motions of a rotating disk (10) in a hard disk drive (13), and includes the steps of measuring a base plate roll-bias angle between the rotating data storage disk and the head arm (15) with a precision measuring device, and connecting the head arm and load beam (17) 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.
