Nano / MEMS enabled HDD modeling • Areas covered in modeling aspects of Nanotechnology and HDD its implications on current data storage mediums have been exemplified. We have elucidated the influence of recent advances of Nano-Composites, MEMS (Micro Electro Mechanical Systems) etc. and their implications towards the development of storage devices in the future.

Actuators and Heads • Modeling of Comb drive actuator in SUG AR for HDD applications • Most of the research on MEMS enables devices in HDD has been on MEMS based actuators and heads. 2
