Abstract
A method of forming a bit patterned media on a magnetic media disk may include forming topographic features on a substrate and defining trenches therebetween. The method also may include forming non-magnetic material on the topographic features to define non-magnetic portions. In addition, magnetic material may be formed on the non-magnetic portions to define magnetic portions for a recording layer, such that the magnetic portions have a magnetic width that is greater than a non-magnetic width of the non-magnetic portions.
