Highly chemically ordered and textured L10FePtX-Y (001) granular media with sufficient perpendicular magnetic anisotropy are key approaches for future high areal density heat-assisted magnetic recording (HAMR).  X=Cu, Ag etc. reduces the Curie temperature and Y=Carbon, SiO2 etc. decouples the grains.  Texture and heat sink layers optimize the recording speed and achievable areal density beyond 1Tb/in2. This talk will summarize the ongoing HGST HAMR media efforts including experiments and modeling. Included are challenges and required research and development efforts based on joint discussions between HGST, Seagate and Western Digital at ongoing Advanced Storage Technology Consortium (ASTC) meetings.
