Analysis of the Influence of the Ramp and Disk Dynamics on the HDI Response of 2.5-in Hard Disk Drive to a Shock

Operational shock (op-shock) analysis has been developed to consider the dynamics of components of a hard disk drive (HDD). Op-shock simulation uses simplified models. However, the dynamics of the components affect the head-disk interface (HDI) response, especially the disk curvature and ramp-disk c...
