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 translation: 数据写入元件可以被配置成至少具有沿着第一轴定位在第一屏蔽附近并且沿着第二轴相邻于第二屏蔽的写入极。 第二屏蔽件可以在空气轴承表面（ABS）上的第一间隙距离和离开ABS的第二间隙距离处与写入极分离，第一和第二间隙距离在平行于ABS定向的过渡表面处相遇。

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.
