摘要： Embodiments of the invention generally relate to PFPE lubricants, and more specifically to increasing the conductivity of PFPE lubricants. PFPE lubricants generally have low polarity and do not dissolve most conductive additives that tend to be highly polar. However, hydrophobic ionic liquids are highly fluorinated and have low polarity. Therefore, the hydrophobic ionic liquids may be dissolved in a PFPE lubricant to increase the conductivity of the PFPE lubricant.

摘要： A system and method for reducing corrosion in a fluid dynamic bearing is disclosed. In one embodiment, a fluid dynamic bearing comprising a rotor portion and a stator portion is formed. In addition, a corrosion inhibitor containing lubricating fluid is provided between the rotor portion and the stator portion of the fluid dynamic bearing, wherein the corrosion inhibitor containing lubricating fluid does not react with either the rotor portion or the stator portion of the fluid dynamic bearing.

摘要： A polishing system and associated methods are described for polishing a magnetic disk used in a disk drive system. The polishing system includes a polishing film that is used to polish the magnetic disk. The polishing system also includes an actuator operable to move the polishing film across a surface of the magnetic disk to polish the magnetic disk. The polishing system also includes a pad having at least one protrusion extending from a surface of the pad. The protrusion is configured to contact the polishing film and press the polishing film against the magnetic disk. The protrusion is operable to compress to about the surface of the pad when in contact with the polishing film. Once polishing is complete, the pad retracts from the polishing film and the protrusion extends from the pad, reducing the adhesion force between the pad and the polishing film.

摘要： Lubricant with non-terminal functional groups. The location of the functional groups minimizes free chain length and molecular weight of a lubricant while simultaneously maximizing evaporation temperature. The locations of the functional groups to the backbone of the molecule of the lubricant allows for shorter lengths of free backbone length between functional groups attached to a lubricated surface. The lubricant lubricates mechanical devices including hard disk drives.

摘要： A magnetic read/write head is produced with an insert layer between the substrate and the magnetic transducer. The insert layer has a lower coefficient of thermal expansion than the substrate, which reduces the temperature pole tip recession (T-PTR) of the head because the insert layer is an intervening layer between the substrate and magnetic transducer. The insert layer is produced by plating, e.g., an Invar layer over the substrate prior to fabricating the magnetic transducer. The Invar layer is annealed and the structure planarized prior to depositing a non-magnetic gap layer followed by the fabrication of the magnetic transducer.
