The embodiments disclose an apparatus including at least two carbon source deposition tools for emitting electrons, at least two reflective polarity rear button permanent magnets integrated into the carbon source deposition tools for reflecting emitted electrons, and at least two paired polarity Helmholtz coils integrated into the carbon source deposition tools for forming uniform parallel magnetic field lines for confining the emitted electrons to uniformly deposit carbon onto the surfaces of a two-sided media disk.

Helmholtz coil assisted PECVD carbon source

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.

Coil filament for plasma enhanced chemical vapor deposition source

A chemical vapor deposition source that includes at least one plate to which first and second electrical connection posts are coupled. The chemical vapor deposition source also includes a filament having a first end and a second end. The first end of the filament is electrically connected to the first electrical connection post and the second end of the filament is electrically connected to the second electrical connection post. The chemical vapor deposition source further includes at least one filament holder electrically insulated from the at least one plate. The at least one filament holder holds a portion of the filament between the first end and the second end.

Filament holder for hot cathode PECVD source

A magnetic data storage medium may include a substrate, a magnetic recording layer, a protective carbon overcoat, and a monolayer covalently bound to carbon atoms adjacent a surface of the protective carbon overcoat. According to this aspect of the disclosure, the monolayer comprises at least one of hydrogen, fluorine, nitrogen, oxygen, and a fluoro-organic molecule. In some embodiments, a surface of a read and recording head may also include a monolayer covalently bound to carbon atoms of a protective carbon overcoat.

Covalently bound monolayer for a protective carbon overcoat

A device having an air bearing surface, the device including a writer portion having an air bearing surface at the air bearing surface of the device; and an overcoat layer disposed on at least a portion of the air bearing surface of the writer portion, wherein the overcoat includes a material having a magnetic moment of at least about 0.1 Tesla (T).

Overcoats that include magnetic materials

A substrate having a carbon-deuterium protective overcoat layer, and method for making the same. In some embodiments, the substrate includes a recording structure having a magnetic recording layer. A protective overcoat layer is Formed on the recording structure, the protective overcoat layer composed of carbon-carbon (C&#x2014;C) and carbon-deuterium (C-D) bonds and having no carbon-hydrogen (C&#x2014;H) bonds.

Carbon-deuterium protective overcoat layer

A transducing head includes a first bias element, a second bias element, and a magnetoresistive sensor positioned between the first bias element and the second bias element. The first bias element and the second bias element are each formed of a permanent magnet material having a remanent magnetic moment in a range of about 200 to about 800 emu/cm. In a preferred embodiment, the permanent magnet material is an alloy comprising iron, platinum, and at least one material selected from copper, silver, magnesium, lead, zinc, bismuth, and antimony.

Magnetoresistive transducer with low magnetic moment, high coercivity stabilizing magnets

Magnetic films comprising iridium, manganese and nitrogen (IrMnN) are disclosed. Multi-layer structures including ferromagnetic layers deposited on the IrMnN films are also disclosed. The IrMnN films have a (200) texture and may act as seed layers and/or exchange biasing layers for the ferromagnetic layers deposited thereon. The multi-layer structures are useful in applications such as read sensors for magnetic recording heads and soft magnetic underlayers for perpendicular magnetic recording media.
