“…Pole-tip recession (PTR) has received much attention as it is the main contributor to loss of the head-disk interface during the precision lapping process (Menon, 2000; Khurshudov & Raman, 2005; Tjiptoharsono et al, 2010). In particular, many studies have focused on the effect of a diamond like carbon coating process on PTR (Scott & Bhushan, 2000; Sourty et al, 2002; Chen et al, 2011). Both recession and protrusion of the pole tip should be avoided for optimal performance.…”

The impact of lubricants on pole-tip recession and surface morphology of hard disk drive heads in the precision lapping process was investigated with atomic force microscopy, scanning electron microscopy, and auger electron spectroscopy. In particular, the effects of deionized water, hydrocarbon oil, ethanediol, isopropanol, and ethanol lubricants were evaluated. The results reveal that proper selection of lubricant is critical for achieving optimal performance in the lapping process. A mixture of 68% hydrocarbon oil, 30% isopropanol, and 2% octadecenoic acid was found to yield the most favorable results, displaying a writer shield recession, first shield of reader recession, and surface roughness of 0.423, 0.581, and 0.242 nm, respectively.

“…Brown stains were been observed on magnetic heads running against metal particulate (MP) tape [1][2][3][4][5][6][7][8][9][10][11][12][13]. The occurrence of brown stains is a complex tribological and chemical phenomenon on the head/tape interface.…”

“…Bhushan and Harn reported that the brown stains produced with MP tape indicate primarily an inorganic content of oxidized metal particles from the tape with a small amount of organic constituents chemically different from the tape binder [1]. Sullivan et al reported that brown stains are formed due to metal particle transfer from the tape, produced by adhesive contact between the outer surface of the polymeric tape binder and the head [8][9][10][11]. Brown stains have been observed under high temperatures and low relative humidity (RH) [1][2][3].…”
