    摘要: 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.
