Abstract

Dual stage actuators have recently been implemented in hard disk drive suspensions in order to increase the track density of hard disk drives. This paper investigates the lateral deflection (lateral stroke), stress distribution and design characteristics of a suspension-based and a collocated flexure-based dual stage actuated suspension design using finite element analysis. Design parameters for each suspension design are examined and guidelines for improved lateral deflection characteristics are proposed.
