ENERGY ASSISTED SEGREGATION MATERIAL

摘要

Apparatus ( 102) for recording data and method for making the same. In accordance with some embodiments, a magnetic layer (128) is supported by a substrate (122) and comprises a 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.
