Summary:PROBLEM TO BE SOLVED: To provide thermally assisted data recording media that can provide a slower reduction of the magneto-crystalline anisotropy.SOLUTION: In some embodiments, a thermally assisted data recording medium has a recording layer formed of iron (Fe), platinum (Pt) and a transition metal T selected from the group consisting of Rhodium (Rh), Ruthenium (Ru), Osmium (Os) and Iridium (Ir) to substitute for a portion of the Pt content as FePtTwith Y in the range from about 20 atom% to about 80 atom% and X in the range from about 0 atom% to about 20 atom%.SELECTED DRAWING: Figure 2 【課題】結晶磁気異方性のより遅い低下を与えることができる熱アシストデータ記録媒体を提供する。【解決手段】いくつかの実施形態では、熱アシストデータ記録媒体は、記録層を有し、当該記録層は、鉄(Fe)と、白金(Pt)と、ロジウム(Rh)、ルテニウム(Ru)、オスミウム(Os)およびイリジウム(Ir)からなる群から選択される遷移金属Tとから形成され、遷移金属Tは、FeYPtY−XTX(式中、Yは約20原子%〜約80原子%の範囲内であり、Xは約0原子%〜約20原子%の範囲内である。)としてPt含有量の一部を置換する。【選択図】図2
