Abstract
Apparatus for recording data and method for making the same. In accordance with some embodiments, a magnetic layer is supported by a substrate and comprises a magnetic magnetic material, a non-magnetic material, and an energy assisted segregation material. The segregation material enhances segregation of the non-magnetic material into grain boundaries within the layer at an elevated, moderate energy level.
