Abstract: A data writer may be configured with a write pole that has one or more sidewalls continuously extending from an air bearing surface. A write pole sidewall can have a plurality of different wall angles. A portion of a write pole sidewall contacting the air bearing surface can have a first wall angle with respect to a trailing edge of the write pole, parallel to the air bearing surface. A second portion of the write pole sidewall can be half or less of the first wall angle. A third portion of the write pole sidewall can be smaller than the second wall angle.

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.

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 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 recording head that includes a bearing surface and a write pole having a front surface that forms a portion of the bearing surface. The recording head also includes a side shield for the write pole. The side shield includes a low saturation magnetization cap layer having a front surface that forms a portion of the bearing surface. The side shield also includes a main side shield layer having a saturation magnetization that is higher than a saturation magnetization value of the low saturation magnetization cap layer.
