Abstract

Patterned media are being considered as a promising approach for achieving storage densities beyond 1 Tb/in2 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 femto-type sliders over bit patterned media (BPM) are investigated. The discrete bits of the disk are modeled as isolated conical protrusions on the disk surface.
