Abstract
This paper investigates bits transition shift written by a trapezoid single pole at a large skew angle. This work uses the even harmonic ripple effect to modulate the demagnetization field and observe the transition shape clearly. Experiment results indicate that the trapezoid single pole can produce a twisted transition at a large skew angle. This phenomenon is mainly due to the low-frequency data overwriting on the media. The twisted transition will limit the recording density in the perpendicular recording. Simulation work was completed to validate our experiment results. It suggests that the structure of single pole should be further improved to solve the twisted transition generated by the trapezoid single pole.
