Abstract: A thin film structure for a magnetic thin film recording medium including a dual seed layer of RuAl/NiAlB is disclosed. The use of the RuAl/NiAlB structure provides reduced grain size, an increased Mrt orientation ratio (OR), increased SNR and lower PW50 at higher amplitude. The RuAl and NiAlB seed layers each have a B2 crystallographic structure. The RuAl/NiAlB dual seed layer can be used to obtain an underlayer with a preferred in-plane orientation of (200) and a cobalt alloy magnetic film with the preferred in-plane orientation of (11{overscore ( )}20).

Abstract: Fabrication methods for magnetic recording media that use a plasma polish are disclosed. For one exemplary method, a film of a magnetic recording medium is deposited, and a top surface of the film is polished utilizing a plasma formed by a noble gas to smoothen the top surface of the film. A subsequent layer is then deposited onto the polished top surface of the film. A top surface of the subsequent layer has a reduced roughness by being deposited on the polished top surface of the film.
