Abstract
Experiments reported in this work indicate that for the same head-disk spacing, the outer diameter, corresponding to higher skew angle, is more sensitive to the spacing variation. Conducted investigations cover peak detection channels, PRML channels, oriented media, isotropic media, and the same conclusion can be drawn. Increased skew angle will increase the nonlinear transition shift in the write process. Such phenomena can be observed from both the isotropic media and the media with strong orientation.
