Methods comprising providing a pre-patterned substrate having an array of thick walls, depositing a conforming layer on the pre-patterned substrate, etching the conforming layer from the top of the thick walls and the space between the walls, and etching the thick walls while leaving thin walls of conforming layer.

Ultra thin alignment walls for di-block copolymer

An apparatus for measuring a distance such as, for example, a fly height distance. An apparatus includes a slider having an air bearing surface and an optical condenser assembly spaced apart from the air bearing surface of the slider. The optical condenser assembly includes an optical cap and an optical substrate having a first surface and a second surface. The first surface is spaced apart from the optical cap and the second surface is spaced apart from the air bearing surface of the slider.

Fly height and slider protrusion measurement

An apparatus includes a component having a first surface, a first waveguide for directing electromagnetic radiation to a focal point adjacent to the first surface, a storage medium positioned adjacent to the first surface, a detector for detecting electromagnetic radiation reflected from the storage medium, and a structure positioned adjacent to the focal point for collecting the reflected electromagnetic radiation and for transmitting the reflected electromagnetic radiation toward the detector, wherein the structure comprises a second waveguide including a first cladding layer positioned adjacent to a first side of the first waveguide and having a first end positioned adjacent to the first surface and a second cladding layer positioned adjacent to a second side of the first waveguide and having a first end positioned adjacent to the air bearing surface.

Optical recording using a waveguide structure and a phase change medium

An apparatus comprises a waveguide, an optical transducer for coupling electromagnetic radiation from the waveguide to a point adjacent to an air bearing surface to heat a portion of a storage medium, and a first wire positioned adjacent to the air bearing surface, wherein current in the wire produces a magnetic field in the heated portion of the storage medium.

Dual wire integrated WAMR/HAMR writing head

An apparatus comprises a slider having an air bearing surface, a first waveguide for directing electromagnetic radiation to a focal point adjacent to the air bearing surface, a storage medium position adjacent to the air bearing surface, a detector for detecting electromagnetic radiation reflected from the storage medium, and a structure positioned adjacent to the focal point for collecting the reflected electromagnetic radiation and for transmitted the reflected electromagnetic radiation toward the detector.
