... unloading was accounted for to develop an improved coefficient of restitution model. The impact model was applied to study a practical case of a cylindrical feature on the slider of a magnetic storage hard disk drive impacting the disk to predict various critical impact contact parameters. The CM model...

...Raja R. Katta; Andreas A. Polycarpou; Sung-Chang Lee; Mike Suk Scratch-related magnetic signal degradation can occur during magnetic storage hard disk drive operations when the read-write heads contact the spinning multilayer disks. To investigate this phenomenon, controlled nanoscratch experiments...

... magnetic storage The storage market is presently dominated by hard disk drives. However, magnetic tape has maintained its cost-per-gigabyte advantage with respect to hard disk drives and remains the primary choice for backup and mass data storage applications ( 1 2 ). Tape research can...

... and loading decreases in applications such as MEMS, NEMS and magnetic storage devices measurement of flash temperature becomes increasingly more difficult due to the nanometer scale asperity interactions. Consequently measurement of flash temperature at the nanoscale asperity contact has not yet been possible...

...Allison Y. Suh; Andreas A. Polycarpou Preferential surface texturing is expected to significantly improve tribological performance of ultralow flying magnetic storage head-disk interfaces (HDIs) by modifying the roughness and reducing the contact area preferentially, thereby reducing the relevant...
