    摘要： Method, with structure, of production of precision head/disk interfaces for near contact recording in a low viscosity liquid lubricant film. Triangular shaped bearing pads in an assembled hard drive are brought to bear upon a rotating lubricated disk to dislodge, smooth and polish any residing asperity. The triangular shape of the bearing pads sweeps away and directs to the outer edge of the disk any of the remaining fine carbon sputtering debris which is loosened as the bearing pads are drawn from the inner dimension to the outer dimension of the disk.

    摘要： An integrated head-suspension-wick system having lubrication, including a bearing area at one end that holds a magnetic transducer against the disk. The invention provides wicking grooves in the integrated head-suspension-wick arm. The grooves are shaped to cause capillary forces to pull the lubricant from the supply wick on the arm, along the suspension of the bearing area. This ensures that the disk area under the head will not go dry regardless of storage duration or conditions. When the disk is running, the wick continues to conduct lubricant to the disk surface.

    摘要： A thin film magnetic recording disk that has a layer of lubricant bonded thereto is enclosed within a vapor phase lubricant system that operates to continuously apply lubricant vapors to the disk's bonded lubricant layer by operation of Langmuir kinetics. Lubricant vapors are selectively adsorbed on the disk, including regions of the disk where the bonded lubricant is either too thin or is entirely absent, thus minimizing failures that might be caused by such imperfections in the bonded lubricant layer. A reactive perfluoropolyether (PFPE) lubricant containing chemically active functional groups is substantially bonded onto the recording surface of the disk, for example by the application of heat. The mobile residue of this bonded lubricant layer may be left on the disk, to thereafter function as a non-bonded, mobile, lubricant layer covering the surface of the bonded lubricant layer. Alternately, the lubricant residue may be substantially removed by use of a solvent or other means, and a nonreactive lubricant, such as a nonreactive PFPE, may thereafter be topically applied onto the surface of the bonded lubricant layer, to function as a non-bonded, mobile, lubricant layer. A lubricant reservoir within the vapor phase lubricant system provides a supply of a volatile organic lubricant, such as stearic acid or reactive or a nonreactive PFPE. Lubricant vapors from this reservoir operate so as to continuously repair voids or thin areas in the disk's simplex layer of substantially bonded lubricant, or in the disk's duplex layer of bonded and mobile lubricant. Either one, two or three lubricants could be used in this tribological system.

    摘要： The lubricant film for a near contact magnetic recording device is maintained by a closed loop servo control for a recirculating lubricant supply system. A reservoir closely overlies the disk data surface and includes a heater for controlling the temperature difference between the reservoir and the disk surface. Decreasing the heater current reduces the film thickness and increasing the heater current increases the film thickness. A wick system gathers lubricant from within the disk enclosure, which may have been spun off the disk or condensed from the lubricant laden atmosphere and returns the lubricant by capillary action to the reservoir. Further, the reservoir includes two portions which are independently controllable. The first overlies the data band of the disk and the second overlies the start/stop zone and the head when the latter is not operational and parked at the nonoperating location. The start/stop zone reservoir can be used to increase the localized film thickness when the head is coming to rest on the disk surface and during start-up to prevent wear between head and disk.

    摘要： A rotating magnetic storage device is shown wherein the transducer and media are separated during operation by a thin film of low viscosity liquid lubricant that is recirculated from a reservoir within the head-media enclosure. Lubricant recirculation can be effected by capillary action using a wick, mechanical pumping and metering or distillation techniques. As compared to devices using air bearing separation, the transducer carrying slider has very small bearing surfaces which may be in the form of narrow rails or small depending foot elements. This enables fly heights of 2 microinches using a film of one micron thickness.
