Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A writer comprising: a write element including a tip portion to generate a write field during a write operation; and a conductive assembly that is configured to deliver 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.…
