摘要:
A writer for perpendicular recording on bilayer media with suppressed skew angle effect on the width of the recorded track is disclosed. The writer has a wide and flat trailing edge and a narrow leading edge. In a preferred embodiment, the pole has a trapezoidal cross-section. To suppress the skew effect on the width of the recorded track, the slope angle of the pole sides may be greater than the maximum skew angle in a drive.
