    Abstract: An apparatus includes a write pole magnetically coupled to write coils that generate a first magnetic field during a switching event. The apparatus includes a shield at a media-facing surface and proximate the write pole. A conductive element is disposed proximate the shield and configured to generate a second magnetic field opposite to the first magnetic field during the switching event. A selected one of the write coils is located adjacent the shield separate from others of the write coils.

    Abstract: A recording media design having discrete track recording structure where the trenches between tracks are filled with a soft magnetic material is provided. The soft magnetic material provides a low magnetic impedance path to the soft underlayer such that fringe fields from the write head are conducted to the soft underlayer without having a negative effect such as adjacent track erasure. A method of manufacturing the media includes a nano-imprint step and ion milling out the data layer to create the trenches. A B2O3 material allows the data layer to be ion milled out without redeposition bridging the B2O3 layer thus preventing lift off of the mask. The trenches are then filled by ion deposition with the layers of ferromagnetic material separated by an anti-ferromagnetic coupling that causes the flux to be conducted to the soft underlayer and remnant flux to rotate within the island and not into adjacent tracks.

    Abstract: A write head has a pole tip, a write yoke connected to the pole tip, a write return yoke, a write shield, and one or more side shields disposed in close proximity to the pole tip. The write return yoke connects to the write yoke on one end and the write shield on a different end. The one or more side shields are separated from the pole tip and write shields by a non-magnetic material and therefore are “floating” and not directly coupled to the write shield or pole tip.

    Abstract translation: 写头具有极尖,与磁极尖连接的写磁轭,写回位磁轭,写屏蔽以及设置在极尖附近的一个或多个侧屏蔽。 写入返回磁轭在一端连接到写磁轭,而在另一端连接写屏蔽。 一个或多个侧面屏蔽件与极尖分离,并由非磁性材料写入屏蔽,因此“浮动”并且不直接耦合到写入屏蔽或极尖。

    Abstract: A data writing device may be constructed and operated with at least a data writer that has at least a write pole and a magnetic feature. A controller may selectively activate the magnetic feature to magnetically oscillate and produce a radio frequency signal proximal the write pole on an air bearing surface (ABS).

    Abstract: A data writer may be configured with at least a write pole and a continuous coil with the continuous coil having a first turn with a first cross-sectional shape and a second turn with a second cross-sectional shape that differs from the first cross-sectional shape. The second turn may be positioned proximal a leading edge of the write pole and an air bearing surface while the first turn is positioned distal the air bearing surface.
