Abstract
A writer includes a write element having a tip portion to generate a write field during a write operation and a conductive assembly that delivers a write assist current through the tip portion in a cross-track direction to generate a write assist field during the write operation that extends beyond a medium confronting surface located at the tip portion to lower a coercivity of a magnetic medium proximate to the write element.
