Abstract

This paper presents the current status of hard disk drive (HDD), three key mechanical components, their common features of positioning mechanism, and various nanodynamic problems to be studied for the development of a higher density and higher performance HDD. Then I show our recent study of the nanodynamics of a flying slider in a near-contact regime and interfacial adhesion forces caused by lubricant meniscus. In the head positioning mechanism, tracking error caused by disk flutter and flow-induced head arm/suspension system is described. We proposed a squeeze air damping plate to suppress the disk flutter, and a dynamic absorber design to suppress the flow-induced suspension vibration.
