Abstract
This article discusses the advantage and potential of air bearing being used in hard disk drive (HDD) to replace the conventional oil-lubricated bearing HDD. The designing of these air-lubricated bearing is conducted with the optimization of bearings groove designs through the combination of direct search and Successive Quadratic Programming (SQP) method. Characteristics compared to the conventional oil-lubricated bearings of a spiral groove showed promising improvements where a new geometry of a modified spiral groove has been found. The new design holds higher performance characteristics compared to the conventional spiral grooved bearings and the calculation results are shown.
