Abstract

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 adhesion and slider-lubricant and slider-disk contacts. The basic design conditions for a stable surfing HDI are also discussed.
