Abstract: An apparatus is disclosed. The apparatus includes a storage layer, a first write layer, and a second write layer. The first write layer is disposed over the storage layer. The second write layer is disposed over the first write layer. The anisotropy field and magnetization associated with the second write layer at writing temperature is greater than anisotropy field and magnetization associated with the first write layer at the writing temperature.

Abstract: A device includes a housing unit and a number of magnets. The housing unit includes a number of holes therein. The magnets are positioned in the holes. The magnets have a same pole orientation. It is appreciated that the magnets are positioned in the holes to form a mechanically balanced and magnetically unbalanced structure.
