Abstract: A data writer may be generally configured at least with a write pole adjacent to and separated from a side shield and a trailing shield. The side shield may be formed of a first material and configured with a trailing box region that is at least partially filled with a flux density insert formed of a second material that is different than the first material.

Abstract: A data storage system may have at least one data writer that incorporates a write pole that continuously extends from an air bearing surface. The write pole can be separated from the air bearing surface by a side shield that consists of a first magnetic layer positioned on the air bearing surface and a guard layer separated from the air bearing surface by the first magnetic layer. The guard layer may be configured with a different magnetic saturation flux density than the first magnetic layer.

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 writing element may be configured at least with a write pole positioned adjacent a first shield along a first axis and adjacent a second shield along a second axis. The second shield may be separated from the write pole by a first gap distance on an air bearing surface (ABS) and by a second gap distance distal the ABS with the first and second gap distances meeting at a transition surface oriented parallel to the ABS.

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.
