“…They derived an empirical equation for the flying height loss as a function of groove width, track pitch and groove depth and observed that the pitch angle of the slider was nearly independent of DTR parameters. Peng et al [15] predicted the flying height loss of DTR media using an averaged flow model, and verified their predictions by touchdown pressure measurement. Recently, Yoon and Talke [16] found that discrete track recording disks exhibit larger hysteresis between touch-down and take-off than smooth disks.…”

Patterned media are being considered as a promising approach for achieving storage densities beyond 1 Tb/in 2 on hard disks. Patterned media reduce cross talk of adjacent bits and improve thermal stability of the media. In this investigation, the flying characteristics of femtotype sliders over bit patterned media (BPM) are investigated. The discrete bits of the disk are modeled as isolated conical protrusions on the disk surface.

“…Noise from the magnetic material in the trenches can be significant [32,33]. It appears that the trenches can introduce instabilities in the flying [34,35], and thus planarization (at least partial) will likely be required. In addition, there have been recent advances in the RIE of magnetic materials and progress in ion beam etching technologies, partly developed for MRAM applications.…”

Characteristics of molecularly thin lubricant films are basically determined by their interactions with solid surfaces. Since these interactions can be modified by engineered microscopic surface textures, it is expected that rational design of the textures will make it possible to attain desired tribological functions and performance. In this research, with the aim of applying it to head-disk interface of hard disk drives, we propose a method based on diffraction simulations that enables thickness measurement of molecularly thin films coated on grooved solid surfaces. Using this method, we experimentally investigate the spreading characteristics of nanometer-thick polymeric liquid lubricant films on grooved surfaces. The results revealed that the average thicknesses of the films dipcoated on the grooved and smooth surfaces under identical conditions were approximately the same, whereas lubricant spreading on grooved surfaces was significantly faster than that on smooth surfaces.
