Research Abstract

The constant increasing in the recording density of the hard disk is alwaysassociated with the decreasing in the fly height of the magnetic head and it is necessary to reduce the fly height to 2-3 nm for 1Tb/in2. A monolayer PFPE liquid film is coated over the hard disk surface to prevent the contamination. In this study in-situ observation of air bearing surfaces by using a high speed microscope camera was conducted and the flow behavior of adsorbed film was clarified.
