Data storage systems are provided. Data storage systems illustratively include a writing element and a recording medium. In some embodiments, the writing element generates first and second magnetization fields that respectively record first and second magnetization patterns to the recording medium. In some embodiments, the writing element is de-saturated between recording the first and second magnetization patterns.

A write pole structure includes a write pole having a tip region. A shield structure is spaced from the write pole by a gap at the tip region. The shield structure includes a front shield and a spacer layer on the back of the front shield. A yoke is formed on the write pole, and an end of the yoke is aligned with the back end of the spacer layer.

A perpendicular magnetic recording medium comprises a non-magnetic substrate having a surface; and a plurality of overlying thin film layers forming a layer stack on the substrate surface, the layer stack including a magnetically hard perpendicular magnetic recording layer structure and an underlying soft magnetic underlayer (SUL), the SUL having a thickness of up to about 100 Å. Also disclosed is a data/information recording, storage, and retrieval system comprising the perpendicular magnetic recording medium and a single-pole magnetic transducer head including main and auxiliary poles positioned in spaced adjacency to an upper surface of the layer stack, the single-pole transducer head comprising a front shield adjacent the main pole.

A pole tip shield for a write element of a recording head is disclosed. The pole tip shield is spaced from the pole tip in the leading edge direction to provide a magnetic wall angle to reduce ATI or adjacent track erasure to compensate for the skew angle of the head. In illustrated embodiments, the pole tip shield includes side portions. In illustrated embodiments the pole tip shield is generally “U” shaped and side portions of the pole tip shield include different thickness or width dimensions. In illustrated embodiments, the pole tip shield provides a magnetic wall angle for a rectangular shaped pole tip. Embodiments disclosed in the application include a trailing edge shield separated from the pole tip shield along an air bearing surface of the head by a non-magnetic gap portion.

in certain embodiments, an apparatus includes a write pole tip having a top side that has a monotonically decreasing slope that forms a convex profile between a write pole paddle and an air bearing surface.In certain embodiments, an apparatus includes a write pole tip having a first and second top bevel. The first top bevel is at an angle greater than the second top bevel with respect to a plane perpendicular to an air bearing surface of the write pole tip.

An apparatus illustratively includes a return pole (RP) and a shield. The RP has a first RP magnetic layer, a second RP magnetic layer, and a RP non-magnetic layer. The RP non-magnetic layer separates and magnetically decouples the RP first and second magnetic layers. The shield has a first shield magnetic layer, a second shield magnetic layer, and a shield non-magnetic layer. The shield non-magnetic layer separates and magnetically decouples the shield first and second magnetic layers. A method illustratively includes generating magnetic flux and collecting the magnetic flux through an inner magnetic shell.
