Abstract :
In this paper, the author highlight challenges and opportunities in the currently ongoing HAMR media development. This will include moving from spherical grains to vertically more columnar and laterally more Voronoi-shaped grain growth, reducing the number of misaligned in-plane grains in the media layer for obtaining full remanent moment, lowering sigma TC distributions and identifying possible sources of undesired sigma T distributions.
