Abstract :
Sliders flying over patterned or discrete track media are exposed to an entirely different pressure field from the air bearing than in the case of present day "smooth" disks. In this first study, we investigate the influence of discrete track media parameters such as groove width, groove pitch, and groove depth on the steady-state flying characteristics of five different slider designs using a finite-element-based air bearing simulator
