摘要: 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.
摘要翻译: 写入器包括具有尖端部分的写入元件,用于在写入操作期间产生写入场,以及导电组件,其在交叉轨道方向上传递写入辅助电流通过尖端部分,以在写入操作期间产生写入辅助场, 延伸超过位于尖端部分的介质面对面以降低靠近写入元件的磁性介质的矫顽力。
