Abstract
A system comprises a first tapered core configured for positioning adjacent a first surface of a magnetic medium, and a second tapered core configured for positioning adjacent a second surface of the magnetic medium, opposite the first tapered core along a travel direction of the magnetic medium. Each of the first and second tapered cores has a transverse width defined with respect to the magnetic medium, where the transverse width decreases from a first end of the tapered core to a second end of the tapered core, the second end forming a pole face adjacent the magnetic medium.
