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.

An apparatus comprising:
- a magnetic layer supported by a substrate, the magnetic layer comprising a magnetic material, a non-magnetic material, and an energy assisted segregation material adapted to enhance segregation of the non-magnetic material into grain boundaries within the layer at an elevated, moderate energy level.
An apparatus comprising:
- a magnetic layer supported by a substrate, the magnetic layer comprising a magnetic material, a non-magnetic material, and means for enhancing separation of the magnetic material into grains at an elevated, moderate energy level.
A method comprising depositing on a substrate a magnetic layer comprising a magnetic material, a non-magnetic material and an energy assisted segregation material at an elevated, moderate energy level comprising a substrate temperature of from about 25° C. to about 220° C. and a substrate voltage magnitude of from about 0V to about 500V, wherein during said depositing step the segregation material enhances segregation of the non-magnetic material into grain boundaries within the layer.
