Abstract :
Design margin of position error signal (PES) is getting smaller as track density of high-capacity disk drives increases. A substantial portion of the PES is caused by disk vibration which makes off-track between head and disk. In this paper, a new HGA design concept is introduced for suppressing the off-track due to disk vibration as well as the off-track due to suspension bending.
