Skew Angle and Head-Disk Integration for Gb/in^2 Areal Density Recording

抄録

Skew angle and its effect to the head-disk integration for the Gb/sq-in areal density recording were studied systematically and reported. The results presented in this paper covers the skew angle effect on read/write performance, bit and track densities, landing zone tribology performance, off-track capability, noise and so on. High skew angle reduces the potential of bit density, increases the noise level, and increases the long term stiction in the take-off process in the landing zone. Isotropic and anisotropic media were studied on the skew angle effect. Media with different orientation ratio were used in the investigation.
