Study of lubricant-coated sliders showed that low slider surface energy increases in stable slider flying and reduces lubricant droplet formation on the disk surface at ultra-narrow clearance. Both component- and drive-level evaluation showed the lubricant pick-up and the flying height it causes were reduced significantly. Furthermore, there was no magnetic spacing increase at the drive-level for the lubricant-coated slider when using contact detection to set the clearance methods.
