Research Abstract

The objective of this research project is to analyze the static and dynamic characteristics of near contact heads considering the interactions between molecular gas film lubrication (MGL) effects and molecular liquid film lubrication (MLL) effects which are indispensable for ultra thin physical spacings between recording head and disk. We established highly accurate simulation scheme and measurement methods for ultra-high density magnetic recording system.
