Bit-shift performance investigations at different skew angles and for different media orientations

Abstract

Bit-shift performance was investigated at different skew angles and for media with different orientation. Results indicate that the bit-shift value increases as the skew angle increases for both planar orientated media and near-isotropic media. As the skew angle increases, the off-track capability, described by the bit shift at different off-track distances, decreases and the bit-shift profile becomes asymmetric. Comparison of normalized bit-shift values (normalized according to the bit shift at 0° skew angle) shows that the bit shift of the near-isotropic media is not as sensitive to skew angle variation as the media with strong orientation. © 1996 American Institute of Physics.
