Abstract: A composite disk-clamp assembly including a clamp or spacer of a resilient material coupled to a disk by injection molded plastic so that the clamp forms an integral portion of the disk itself.

Abstract: 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.

Abstract: 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.

Abstract: A clamp includes a disk and a clamp engaging the disk, wherein the clamp has protrusions that bite into a surface of the disk. A disk and clamp assembly includes a disk having receiving areas formed therein, and a clamp engaging the disk, where the clamp has protrusions that engage the receiving areas. Another disk and clamp assembly includes a disk having protrusions formed thereon, and a clamp engaging the disk, where the clamp has receiving areas adapted for receiving the protrusions.

Abstract: A magnetic brake to prevent rotation of the spindle motor and disk(s). The magnetic brake includes two magnets, one attached to the spindle, clamp, disk, or motor, and the other magnet is coupled to the drive housing or to a movable member. Before the drive is installed in a computer, storage array, etc., the magnet coupled to the housing is removed externally, or the movable member is moved to free rotation of the spindle motor and disk(s). The movable member can also be caused to move automatically when a cable is attached to the drive. An alternate embodiment wraps a wire coil around one of the magnets to counter its magnetism upon energization, freeing the spindle motor and disk(s).

Abstract: A device for extending an event time of a physical shock imparted on an electronic device. The device includes a rigid or semi-rigid frame and a resiliently elastic material coupled to the frame, the resiliently elastic material suspending an electronic device with respect to the frame. The resiliently elastic material may be in the form of a sheet, a strap, a rib, and combinations thereof. One preferred resiliently elastic material is a polymeric material.

Abstract: 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.
