Abstract: A first trench sidewall has a continuous first taper angle that terminates at a first plane. At least one layer may be deposited that forms a second trench sidewall with a continuous second taper angle that extends a predetermined depth past the first plane and is less than the first taper angle. A write pole may then be formed on the second trench sidewall with the write pole being closer to the first trench sidewall at the predetermined depth than at the first plane.

Abstract: A magnetic writer includes a write pole configured such that the easy magnetic axis is parallel to the vertical length direction of the write pole tip and to the ABS of the recording media. The write pole tip can be a multilayer structure comprising alternating magnetic and nonmagnetic layers with a planar orientation substantially perpendicular to the ABS and with magnetic anisotropy parallel to the vertical length direction of the write pole tip. The alternating magnetic and nonmagnetic layers may be formed by electroplating on a conformal seedlayer in a trench, or by static off axis physical vapor deposition.

Abstract: A patterned magnetic recording media and method thereof is provided. A recording layer comprises a continuous surface of more-noble elements and less-noble elements, such as CoXYZ, wherein X can be Pt, Pd, Ru, Rh, Ir, Os, or Au, wherein Y can be null or Cr, and wherein Z can be null, Cu, Ta, Ti, O, B, Ag, or TiO2. The recording layer is masked, shielding areas for recording domains and exposing areas between the recording domains. A voltage bias establishes the substrate as an anode in the presence of Pt cathode, in an electrolyte bath. Ions of the less-noble element are anodically removed predominantly from the exposed areas of the recording layer for a controlled time. The controlled time minimizes oxidation of the nobler element and reduces undercutting of the recording domains. The article produced can have separating areas with surfaces substantially formed of the more-noble element.
