Dynamic responses of the head-disk interface (HDI) and other mechanical components,
such as suspension, disk, ramp and base are critical to the mechanical robustness of a hard …

Operational shock is one of the key challenges for designing ultrathin mobile hard disk
drives (HDDs) due to the reduced thickness and stiffness of their mechanical components …

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 …

With an increased mobility, hard disk drives (HDDs) now use ramp load/unload technology,
and multiple disks are used to increase the data capacity. This can result in contact between …

Micromagnetics is a continuum theory describing magnetization patterns inside
ferromagnetic media. The dynamics of a ferromagnetic material are governed by the Landau …

This paper presented a coupled field analysis method to integrate the air bearing model with
the structural finite element (FE) model of the full hard disk drive (HDD), including the all …
