摘要： A disc drive slider includes a slider body and a rail formed on the slider body. The rail includes a bearing surface which faces a surface of a disc. A textured portion is formed on the bearing surface of the rail. Pads are deposited on the textured portions. The pads operate to reduce stiction, dynamic friction, and the likelihood of damage to the slider or the surface of the disc due to contact therebetween.

The solid portion has a width which is greater than a resolution of the exposure tool. The sub-resolution line portions have widths which are less than the resolution of the exposure tool. Each of the sub-resolution line portions is spaced apart from the solid portion and from the others of the plurality of sub-resolution line portions by less than the resolution of the exposure tool.

摘要： A sensor supported by a head transducer has a temperature coefficient of resistance (TCR) and a sensor resistance. The sensor operates at a temperature above ambient and is responsive to changes in sensor-medium spacing. Conductive contacts connected to the sensor have a contact resistance and a cross-sectional area adjacent to the sensor larger than that of the sensor, such that the contact resistance is small relative to the sensor resistance and negligibly contributes to a signal generated by the sensor. A multiplicity of head transducers each support a TCR sensor and a power source can supply bias power to each sensor of each head to maintain each sensor at a fixed temperature above an ambient temperature in the presence of heat transfer changes impacting the sensors. A TCR sensor of a head transducer can include a track-oriented TCR sensor wire for sensing one or both of asperities of the medium.

摘要： A multilayer coating of fullerene molecules is deposited on a substrate, and layers of the multilayer coating are removed leaving an approximate monolayer coating of fullerene molecules on the substrate. In some embodiments, a beam generator, such as an ion beam, electron beam or laser generator, produces a beam arranged to break the weaker fullerene-to-fullerene intermolecular bond of the multilayer coating and inadequate to break the stronger fullerene-to-substrate association/bond of the coating. The beam is directed at the multilayer coating to break the fullerene-to-fullerene intermolecular bond. In other embodiments, the monolayer of fullerene molecules is formed by applying a solvent to the multilayer coating to break the fullerene-to-fullerene intermolecular bond of the multilayer coating.
