Devices having an air bearing surface (ABS), the devices include a write pole; a near field transducer (NFT) including a peg and a disc, wherein the peg is at the ABS of the device; an overcoat, the overcoat including a low surface energy layer.

Devices including an overcoat layer

Methods that include depositing a first layer over the entire surface of a structure, the structure having a magnetic reader and a magnetic writer, wherein the magnetic reader and the magnetic writer are positioned adjacent to each other on a substrate and the magnetic writer includes a near field transducer (NFT); depositing a second layer over the entire surface of the first layer; depositing a photoresist material layer over the entire surface of the second layer, the photoresist material layer having a bottom surface in contact with the second layer and an opposing top surface; exposing the photoresist material layer to radiation through the bottom surface of the photoresist material layer via the NFT to form a first exposed region; and exposing the photoresist material layer to radiation through the top surface of the photoresist material layer to form a second exposed region.

Methods of forming magnetic devices with variable overcoats

A magnetic device including: a magnetic reader; a magnetic writer; and a variable overcoat, the variable overcoat positioned over at least the magnetic reader and writer, the variable overcoat having an overcoat layer, the overcoat layer having a substantially constant thickness and material; and at least one disparate overcoat portion, the disparate overcoat portion having a different thickness, a different material, or both, than the overcoat layer.

Magnetic devices with variable overcoats

An air-bearing surface of a slider is coated with a photoresist having a high optical absorbance at or near an operational wavelength of the slider. Light is directed at a target wavelength through an entry of a waveguide integrated into the slider. The light exiting the waveguide forms a feature through the photoresist, the feature proximate a near-field transducer of the slider. A sub-micron pattern is formed using the feature.

Creating a sub-micron pattern proximate a near-field transducer using in-slider waveguide and laser

Disclosed is an embodiment of a suspension for a disk drive having a slider configured for bonding with a gimbal using an adhesive. Embodiments of the slider include one or more cavities in a portion of a slider mounting surface of the slider. The one or more cavities are configured for increasing a volume of the adhesive between the slider mounting surface and the gimbal. A method of forming the one or more cavities on the slider mounting surface, and bonding together the gimbal and the slider is disclosed.

Slider cavity feature for gimbal attachment

An apparatus includes a slider with a cavity in a trailing end of the slider. A laser is positioned in the cavity and has an output facet positioned adjacent to a first wall of the cavity. A cap is connected to the trailing end of the slider and covers the laser.

Capping method for laser diode protection

A method includes: positioning a laser in the cavity in an end of a slider, wherein the laser has an output facet positioned adjacent to a first wall of the cavity to define a first gap between the output facet and the first wall of the cavity, and filling at least a portion of the first gap adjacent to the output facet. An apparatus including a slider including a cavity in a trailing end of the slider, a laser positioned in the cavity and having an output facet positioned adjacent to a first wall of the cavity to define a first gap between the output facet and the first wall of the cavity, and a sealing material filling at least a portion of the first gap adjacent to the output facet is also provided.
