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

An apparatus including a heat sink layer and a magnetic recording layer over the heat sink layer. In addition, a thermochromic layer is over the heat sink layer, wherein the thermochromic layer includes a first optical absorbance at a first temperature and a second optical absorbance at a second temperature.

Apparatuses and methods for absorbing optical energy

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.

Heat assisted magnetic recording media with enhanced tuning exchange coupling

Provided herein is an apparatus including a head over-coat and a depleted region in the head over-coat. A media over-coat is deposited in the depleted region. A near field transducer is adjacent to the head over-coat, wherein the near field transducer combusts the deposited media over-coat.

Selective heat-assisted removal of head over-coat and media over-coat

Provided herein is an apparatus including a substrate and a magnetic recording layer over the substrate. In addition, a thermochromic layer is over the substrate, wherein the thermochromic layer includes a first optical absorbance at a first temperature and a second optical absorbance at a second temperature.

The embodiments disclose a dual-layer magnetic recording structure including a top magnetic layer etched to remove patterned portions of the top magnetic layer and a bottom magnetic layer including portions with altered magnetic properties of molecules to reduce net magnetic moments and including portions of unaltered magnetic properties exchange-coupled through the top magnetic layer.

Dual-layer magnetic recording structure

A shallow trench discrete track media structure is fabricated by etching a magnetic recording layer to provide a plurality of discrete magnetic data tracks separated by shallow trenches. Each shallow trench has a trench floor formed at a depth in the magnetic recording layer that is less than the thickness of the magnetic recording layer. Exposed regions of the magnetic recording layer beneath the trench floor are reacted with reactive plasma to diminish the magnetic moment of the exposed regions.

Shallow trench media

Shallow trench discrete track media (DTM) and pattern transfer process

Systems in accordance with the present invention can include a tip contactable with a media, the media including a substrate and a plurality of cells disposed over the substrate, one or more of the cells being electrically isolated from the other of the cells by a material having insulating properties. One or more of the plurality of cells can include a phase change material. The media is either grounded or electrically connected with a voltage source such that when the tip is placed in contact with the media and a voltage is applied to the tip, a current is drawn through the cell over which the tip is arranged. The current is drawn through the isolated cell at least a portion of the phase change material within the cell beneath the tip is heated to a sufficient temperature such that the material become amorphous in structure. The current is then removed from the phase change material, which is quickly cooled to form an amorphous domain having a resistance representing a '1' (or a '0'). In another embodiment the one or more of the plurality of cells can include a polarity dependent material. In an embodiment, the one or more cells can have a sidewall structure that tapers along the depth of the cell so that the cell has a wider cross-section near where a tip contacts the media and a narrower cross-section near where the cell contacts one of the substrate and an underlayer.
