Abstract
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.
