Abstract

Summary form only given. As the mechanical flying height (FH) decreases towards sub-10 nm in hard disk drives, it is crucial to maintain adequate clearance between the head and the disk for the integrity of the head-disk interface (HDI). Hard disk drives (HDD) with experimental 10 nm flying sliders were tested at ambient condition for 1000 hours at /spl sim/60/spl deg/C. The effects from the radial profile of the FH, the drop in FH at altitude of the slider, the radial variation of take-off height (TOH), the type of lubricant and the curvature of the disks on the mechanical spacing and reliability of the interface are presented.
