Fly and lubricant contact, or surfing recording, is one of interface solutions for 5~10 Tb/in2 of magnetic recording. One of major challenges for surfing schemes comes from how to sustain the dynamic stability of the head disk interface (HDI). This paper explores the mechanism of slider's dynamic stability in surfing on the lubricant by means of an analytical model including air bearings, surface...
A new trailing pad structure with partially-etched pad is proposed. The effect of the pad shape, trench depth and width was numerically investigated and presented. The thermal protrusion efficiency of the new ABS design which has adopted the new trailing pad structure is also presented.
We present an advanced sub-ambient Femto slider that is less sensitive to altitude change. The air bearing design strategy, analysis and optimization are presented. All air bearing simulations were carried out using data storage institute in-house-developed air bearing simulation software.
