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 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 write head for recording data on a storage medium. The write head includes a bearing surface and a write pole. The write pole includes a main pole layer having a front surface that forms a portion of the bearing surface. The front surface of the write pole has a leading edge and a trailing edge. The write pole further includes a high damping material layer. The high damping material layer has a front end that is attached to the main pole layer at the leading edge.

Abstract: A data writer can have at least a write pole laterally disposed between first and second side shields and vertically disposed between a wrap-around shield and a front shield. The write pole may be separated from the side shields and the wrap-around shield by a lamination of first and second non-magnetic layers.

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.
