Abstract: A reaction bottle which includes a container, container top, container interior a bottle cap removeably attachable to the container top, the bottle cap having a cap top and a cap cavity; a septa attached to the bottle cap and configured to releasably seal the container when the bottle cap is attached to the container top; a needle holder attached to the cap top; a hollow needle attached to the needle holder and located in the cap cavity; a needle conduit in fluid communication with the hollow needle; wherein the septa is configured to deform from an at rest state into a punctured state when pressure within the container interior reaches a first threshold value and the septa deforms into the cavity and is punctured by the hollow needle.

Abstract: A disc burnishing head includes an array of burnishing pads and a first and second side rail projecting from a bottom surface of a slider body. The side rails each have an inside surface facing the burnishing pads and an outside surface facing outward. The outside surface of at least the first side rail is serrated. The serrations define a plurality of teeth and notches on the outside surface of the first side rail for cutting, cleaning, and conditioning defects from the surface of a disc.

Abstract: A disc head slider having a slider body that includes a bearing surface, a cavity dam and a sub-ambient pressure cavity is provided. The sub-ambient pressure cavity has a cavity floor, a plurality of sides and a depth that progressively varies between a point on one of the sides and a corresponding point on an opposing side. The depth is measured from the bearing surface to the cavity floor. The cavity floor comprises a plurality of substantially flat bottom surfaces that are separated by at least one elevational change. Other embodiments pertain to other specialized slider cavity configurations.

Abstract: A method of contouring a surface of a slider for supporting a transducer relative to a data storage medium includes applying a lithographic resist layer to the slider surface. The resist layer is then exposed through a single mask having 3a mask pattern defined by variation in an optical density through the mask. The resist layer is exposed in an exposure pattern corresponding to the mask pattern. Portions of the resist layer are removed as a function of the exposure pattern to produce a vertically contoured resist layer. The slider surface is etched through the vertically contoured resist layer during a single etching step to form a vertically contoured surface feature within the slider surface.

Abstract: An air bearing slider includes an asymmetric taper for control of pressurization and suction force formation. The asymmetric taper is disposed on an edge of a slider to accommodate for the speed differential across the disc radial direction, thereby improving take-off performance, reducing sensitivity to skew angle and altitude variation, and reducing the severity of impacts during ramp loading and unloading. A leading taper intersecting a leading surface and air bearing surface of the slider is asymmetric about a longitudinal, bisecting plane of the slider. In another embodiment, side taper intersecting a side surface and air bearing surface of the slider is asymmetric about a latitudinal, bisecting plane of the slider. In another embodiment, rail taper intersecting a rail recess surface and air bearing surface of the slider is asymmetric about a longitudinal, rail-bisecting plane.

Abstract: A disc head slider supports a transducer relative to a data storage disc. The slider includes a slider body having a disc-facing surface with a leading slider edge, a trailing slider edge, and first and second slider corners at opposing ends of the trailing slider edge. First and second rails are disposed on the disc facing surface about a central recess and form first and second bearing surfaces, respectively. The central recess has a depth measured from the first and second bearing surfaces. First and second recessed surfaces are positioned between a trailing edge of the first and second rails and the first and second slider corners, respectively, and are generally coplanar with the central recess. Third and fourth recessed corner surfaces are positioned at the first and second slider corners, respectively, and are recessed from the first and second recessed surfaces.
