摘要:
A sloped reader is disclosed that reduces skew between reader and written transitions in shingled writing. The reader is formed between surfaces of S1 and S2 shields that are aligned parallel to the sloped reader. A PMR writer is described that straightens transition curvature and reduces signal-to-noise ratio in shingled writing. In one embodiment, a symmetrical writer with a bowed trailing edge where two corners have a greater pole height than a center portion may be used for either right corner or left corner shingled writing. In a second embodiment, an asymmetrical writer is formed with a straight and sloped trailing edge such that the write corner has a greater pole height than the opposite corner on the trailing edge. The bowed angle in the symmetrical writer and slope angle in the asymmetrical writer is between 5 and 45 degrees and preferably between 10 and 30 degrees.
