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 vapor deposition source that includes a substantially vertical plate to which first and second filament posts are coupled. The vapor deposition source also includes a filament having a first end and a second end. The filament provides a substantially concentric source of electrons. The first end of the filament is connected to the first filament post and the second end of the filament is connected to the second filament post. The first end of the filament is substantially vertically aligned with the second end of the filament when the filament is connected to the first and second posts.
