    摘要: A device for monitoring lubricant within a disk drive includes a reservoir packet impregnated with lubricant. The reservoir packet is disposed between a first metal screen and a second metal screen such that a lubricant reservoir transducer is created. The capacitance of the lubricant reservoir packet is monitored and when it falls below a predetermined percentage of the initial capacitance, a user is warned to back up the files contained in the disk drive before failure due to lack of lubricant occurs.

    摘要: A data storage system is described with a system for controlling the amount of lubricant being dispensed from the reservoir using a feedback loop that includes at least one sensor output for a physical parameter inside device such as temperature, humidity and fly-height. In one embodiment the lubricant reservoir housing is equipped with a movable shutter over an aperture in the lubricant reservoir housing. The area of the aperture through which the lubricant vapor can pass is controlled by moving the shutter. In another embodiment the lubricant reservoir housing is supplied with a lubricant diffusion packet such as an effusion cell or diffusion tube containing liquid lubricant. An energy source for the lubricant diffusion packet allows the temperature of the lubricant and, therefore, its vapor pressure, to be increased when the need for additional lubricant is sensed. In a preferred embodiment the output from a Quartz Crystal Microbalance (QCM) with an overcoat similar to that used on a disk is used to measure the degree of lubricant saturation inside the drive by sensing the change in the frequency of a crystal oscillator due to the lubricant adsorbing on a surface of the QCM.

    摘要: A method for detecting leakage from a disk drive enclosure includes providing a lubricating composition having a lubricating material and a tag material therein. The tag material has a volatility characteristic that is amenable to analysis. The method includes measuring a concentration of the tag material in the vapor phase. By measuring a concentration of the tag material, a leak rate of the lubricating material can be determined. The lubricating composition may include a perfluoropolyether lubricating material and a halogenated sulfur tag material such as SF6 and/or S2F10.

    摘要: A system in one embodiment includes a disk; a reservoir having a selectively openable cover; a lubricant in the reservoir; and a sensor for detecting an event or condition that triggers opening of the cover. A method in another embodiment includes determining that a trigger event or a trigger condition is occurring or has occurred in a hard disk drive; opening a cover of a lubricant reservoir for allowing egress of lubricant therefrom upon determining that the trigger event or the trigger condition has occurred; and closing the cover of the lubricant reservoir after a period of time. Additional systems and methods are also presented.

    摘要: A method and apparatus for determining the likelihood that a hard-disk drive (HDD) will experience an imminent error in operation is provided. The HDD comprises a differential pressure sensor capable of measuring the difference in the pressure between the interior and the exterior of the enclosure. The differential pressure sensor may reside in a breather filter covering an air passage within the enclosure. The HDD also comprises a risk assessment component capable of (a) determining an expression of how likely it is that the HDD will experience an imminent error in operation based, at least in part, upon the difference in pressure measured by the pressure sensor, and (b) communicating the expression to a user of the HDD. The HDD may optionally comprise one or more of an atmospheric pressure sensor, a particle counter, and a chemical vapor sensor which may be used by the risk assessment component.
