Abstract: A data writer may be constructed and operated as part of a data storage device. The data writer can be positioned proximal a data storage medium. The data writer may have a write pole positioned adjacent a writer coil with the writer coil having a plurality of turns. A controller that is connected to each turn can be adapted to selectively activate less than all the coil turns in response to the data writer being positioned over a first portion of a data storage medium and selectively activate all of the coil turns in response to the data writer being positioned over a second portion of the data storage medium.

Abstract: In certain embodiments, an apparatus may comprise a first output driver connected to a first output via a first trace and a second output driver connected to a second output via a second trace. The first output driver may be configured to output a first drive signal to the first output to drive the first output and the first drive signal may cause first induced noise in the second trace. Further, the second output driver may be configured to output a second drive signal based on the first drive signal where the second drive signal may reduce the magnitude of the first induced noise at the second output.

Abstract: A data writer may be configured with at least a write pole continuously extending from an air bearing surface to a via. The write pole can contact at least one yoke that contacts the write pole. The write pole and yoke may each be disposed between and separated from a write coil that has a single turn and continuously extends to opposite sides of the write pole.

Abstract: A data storage device may have one or more data writers that are configured with at least one write pole and shield. The write pole and shield can each be positioned on an air bearing surface. The shield may have first and second protrusions each extending from a shield body towards the write pole with the first protrusion positioned on the air bearing surface and the second protrusion separated from the air bearing surface and first protrusion by a lateral notch.
Abstract translation: 数据存储设备可以具有配置有至少一个写入极和屏蔽的一个或多个数据写入器。 写入极和屏蔽可以分别位于空气轴承表面上。 屏蔽件可以具有第一和第二突起，每个突起均从屏蔽体朝向写入极延伸，第一突出部位于空气支承表面上，第二突起与空气支承表面分离，第一突起由侧向凹口分开。

Abstract: A data storage device employing a data writer may configure the data writer with at least a write pole that is separated from a front shield on an air bearing surface. The front shield can be arranged to continuously extend from the air bearing surface a first throat height distal the write pole and a second throat height proximal the write pole with the first and second throat heights being different.
