  • Patent number: 10049689
    Abstract: 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.

  • Patent number: 9460746
    Abstract: 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.

  • Publication number: 20160148631
    Abstract: A slider for a data recording device such as a disc drive. The slider has a pattern, which can be a micro-pattern, of SAM material on the air-bearing surface (ABS). The pattern comprises discrete unconnected features, such as dots or lines, that may or may no cover the entire ABS. Methods of micro-printing on the ABS are also provided.

  • Patent number: 9299376
    Abstract: Methods for providing a SAM (self-assembled monolayer) coating on a slider and subsequently removing a portion of the SAM coating. In one implementation, the method includes applying a SAM coating on at least a first surface of a slider and on a second surface of the slider opposite the first surface, and removing at least a portion of the SAM coating from the second surface by irradiating the second surface with UV radiation in a wavelength range of 100-200 nm.

  • Patent number: 8947830
    Abstract: A method for forming an electrical interconnection between a slider pad and a suspension pad that is adjacent to and positioned at an angle relative to the slider pad, which includes the steps of forming a solder bump on a first surface of the slider pad, reshaping the solder bump into a protrusion having an ellipsoidal shape that extends from the slider pad and contacts the suspension pad, and applying a laser to the ellipsoidal protrusion to reflow the solder bump while simultaneously applying a downward pressure to the solder bump in order to form a solder fillet between the slider pad and the suspension pad.
