Abstract :
The flying stability of hard disk drives (HDDs) during operational shock has become increasingly more important as the flying height of the head/disk interface has been reduced to the sub-10 nm flying height regime. In this paper, the dynamic response of a femto slider due to operational shock is investigated. The air bearing is modeled with six linear springs using the ldquodiscrete stiffness methodrdquo.
