摘要： An electrodeposited magnetic recording medium having multiple coercivity values is disclosed. In some embodiments, layers having different coercivity levels may be separated by exchange coupled composites and in other embodiments a range of coercivity levels are deposited in a gradient fashion. In some embodiments, the layers with multiple coercivity values comprise bit patterned media islands formed from a photoresist.

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.
摘要翻译： 提供了一种图案化的磁记录介质及其方法。 记录层包括更贵族元素和较低贵族元素如CoXYZ的连续表面，其中X可以是Pt，Pd，Ru，Rh，Ir，Os或Au，其中Y可以是无效或Cr，以及 其中Z可以为零，Cu，Ta，Ti，O，B，Ag或TiO2。 屏蔽记录层，用于记录域的屏蔽区域和在记录域之间的曝光区域。 在Pt阴极的存在下，在电解质浴中，电压偏压建立了作为阳极的衬底。 较低贵族元素的离子主要从记录层的曝光区域阳极移除一段时间。 受控时间最小化了贵族元素的氧化并减少了记录域的底切。 所制造的制品可以具有基本上由更贵族元素形成的表面的分离区域。
