摘要： A magnetic data storage layer includes a high-Ku alloy and an oxide compound of oxygen and either a single element or an alloy. Because of their high Ku, the magnetic domains of this magnetic data storage layer can be made significantly smaller, while maintaining an acceptable thermal stability ratio of about 50 to 70, to provide areal densities of greater than 200 Gb/in2. Sputter targets for sputtering such a magnetic data storage layer are also provided. The sputter targets include the high-Ku alloy and either the desired oxide compounds, or the elements to be oxidized in a reactive sputtering process. The high-Ku alloy has an anisotropy constant of at least 0.5×107 ergs/cm3.

摘要： A method of manufacturing a magnetic recording medium, including the step of reactively or non-reactively sputtering at least a first data storing thin film layer over a substrate from a sputter target. The sputter target is comprised of cobalt (Co), platinum (Pt), a first metal oxide further comprised of a first metal and oxygen (O) and, when non-reactively sputtering, a second metal oxide. The first data storing thin film layer is comprised of cobalt (Co), platinum (Pt), and a stoichiometric third metal oxide comprising the first metal and oxygen (O). During sputtering, any non-stoichiometry of the third metal oxide in the first data storing thin film layer is compensated for using oxygen (O) from the second metal oxide in the sputter target, or using oxygen (O) from the oxygen-rich gas atmosphere. The first metal is selected from boron (B), silicon (Si), aluminum (Al), tantalum (Ta), niobium (Nb), hafnium (Hf), zirconium (Zr), titanium (Ti), tin (Sn), lanthanum (La), tungsten (W), cobalt (Co), yttrium (Y), chromium (Cr), cerium (Ce), europium (Eu), gadolinium (Gd), vanadium (V), samarium (Sm), praseodymium (Pr), manganese (Mn), iridium (Ir), rhenium (Re), nickel (Ni), and zinc (Zn). The sputter target is further comprised of chromium (Cr) and/or boron (B).

摘要： The various embodiments of the present invention generally relate to the deposition of a seedlayer for a magnetic recording medium used for perpendicular magnetic recording (PMR) applications, where the seedlayer provides for grain size refinement and reduced lattice mis-fit for a subsequently deposited underlayer or granular magnetic layer, and where the seedlayer is deposited using a nickel (Ni) alloy based sputter target. The nickel (Ni) alloy can be binary (Ni—X; Ni—Y) or ternary (Ni—X—Y). In addition, the binary (Ni—X; Ni—Y) or ternary (Ni—X—Y) nickel (Ni) based alloys can be further alloyed with metal oxides, thus forming seedlayer thin films with a granular microstructure containing metallic grains, surrounded by an oxygen rich grain boundary. The nickel-based alloys (with or without metal oxides) of the various exemplary embodiments can be made by powder metallurgical technique or by melt-casting techniques, with or without thermo-mechanical working.
