dc.description.abstract | 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 contact. This paper investigated the effect of the dynamics of HDD components on the HDI response. As the HDD is more sensitive to external shock and vibration, the effects of the dynamics of HDD components need to be considered for accurate op-shock analysis. The ramp-disk contact is an important factor in an op-shock simulation, because ramp-disk contact and disk deformation occur during the shock. Therefore, this op-shock simulation modeled the ramp-disk contact and considered the disk curvature. To obtain an accurate result, a two-way coupled method was used to investigate the HDD dynamic response during op-shock. Using the op-shock model, the fluid-structure coupling effect was investigated and compared with a decoupled model that used linear springs to replace the air bearing. Then, we investigated the effect of the ramp-disk contact and disk curvature on the HDI response during a shock. | - |
