Abstract :
Summary form only given. Shock resistance is becoming very important issue for mobile hard disk drives (HDD). The Taguchi method was applied to designing the suspension in order to improve the shock resistance in operation and non-operation and positioning characteristics. The effects of eight parameters of the suspension shape for three characteristics were investigated. Finally, we optimized three characteristics of the suspension by using a weighted function and developed a high shock resistant head suspension assembly.
