摘要： Magnetic disk drives and associated methods are described for performing an active flying height compensation process for a slider of a magnetic disk drive. For the flying height compensation process, a control system in the disk drive detects a reduction in flying height of a slider in the disk drive. The control system then calculates a compensation heating power to apply to one or more heating elements that are fabricated in the slider to compensate for the reduction in flying height. The control system then applies the compensation heating power to the heating element(s) in the slider to alter the ABS (i.e., generate a protrusion) and increase the flying height of the slider.

摘要： A shock and vibration resistant hard disk drive has a plurality of fluid damping isolation devices disposed between the drive and a supporting frame. The isolation devices are capsules containing either gasses or liquids enclosed in a flexible membrane that spring back to its original shape after the shock or vibration event has transpired. Variation of fluid properties such as density, viscosity, and pressure allow for custom tuning of the vibration and shock performance. In addition, variation of membrane chemistry and thickness of the membrane also allows for further customization. A fuel cell is provided and the isolation devices may provide the energy source for the fuel cell.

摘要： A hybrid drive system for integrated vehicle stability control. Specifically, the hybrid drive system includes a multi-wheeled vehicle, a drop-in electric drive motor, and a master controller. The multi-wheeled vehicle is originally configured for propulsion using an internal combustion engine. That is, the present invention is suitable for powering legacy vehicles. The internal combustion engine capable of driving at least one wheel of the multi-wheeled vehicle. The remaining wheels of the multi-wheeled vehicle are not driven by the internal combustion engine. The drop-in electric drive motor is adapted to independently drive at least one remaining wheel on the multi-wheeled vehicle. The master controller is coupled to the drop-in electric drive motor. The master controller controls speeds of the remaining wheels driven by the electric drive motor to provide propulsion and overall stability management for the multi-wheeled vehicle.

摘要： Embodiments of the present invention recite a method for removing particles from a magnetic head support assembly of a hard disk drive. In one embodiment, a load/unload operation of the magnetic head support assembly is initiated. Particles are dislodged from the magnetic head support assembly by moving it across a physical feature of the load/unload ramp of the hard disk drive. This causes an acceleration of the magnetic head support assembly in a direction substantially perpendicular to its normal plane of movement which dislodges the particles. The particles are then conveyed away from the magnetic head support assembly in an airstream generated by the rotation of the disk pack of the hard disk drive.

摘要： A system and method for monitoring the helium content of a disk cavity of a hard disk drive is disclosed. In one embodiment of the present invention, an oxygen sensor is placed in the disk cavity to monitor the level of oxygen in the cavity. With the measurement of oxygen in the disk cavity, the level of helium in the cavity is inferred. In one embodiment, if the amount of helium inferred from the oxygen level fell below 90%-95% of the gaseous content of the disk cavity, a user is automatically notified in order to maintain the hard disk drive in a timely manner.

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 head slider for a disk drive storage device. The head slider is adapted to fly at the target height above the disk, reduce contamination by preventing particles from being trapped under the head slider, fly well in helium at low velocity and obtain a manufacturing tolerance so that multiple head sliders may be produced and function properly. The head slider has an internal cavity that is substantially enclosed by the air bearing surface. There are two gaps in the air bearing surface that are misaligned relative to the leading edge. The gaps aid in preventing particles from entering the cavity.

摘要： Crater shaped bumps are made on a calibration disk which can be used for calibrating a PZT slider, the PZT slider in turn being used for detecting predetermined asperities on a production run magnetic disk. The crater shaped bumps emulate predetermined asperities of production run magnetic disks and especially asperities which are undesirable and would cause the production run disk to be discarded after testing by the PZT slider. Crater shaped bumps which emulate undesirable asperities on current production runs of magnetic disks have a diameter in the range of 10 to 25 .mu.m and a peripheral ridge with a height h.sub.r above a nominal surface of the calibration disk in the range of 75 to 120 nm. Close tolerance crater shaped bumps with this configuration can be made by impinging two or more pulses of laser energy on the same location of a calibration disk. By increasing the number of pulses the height of the peripheral ridge progressively increases. By employing multiple pulses, the height of the peripheral ridge is increased while the diameter of the crater shaped bump stays substantially constant. Further, by employing multiple pulses diameters and heights of crater shaped bumps can be produced with close tolerances within a diameter range of 5 to 20 .mu.m and a height range of 2 to 120 nm. Different arrangements of the crater shaped bumps on a calibration disk are provided for increasing the range of calibration of the PZT slider.
摘要翻译：在可用于校准PZT滑块的校准盘上形成火山口形凸块，PZT滑块又用于检测生产运行磁盘上的预定凹凸。火山口形凸起模拟生产运行磁盘的预定粗糙度，特别是不期望的粗糙度，并且会在PZT滑块测试后导致生产运行盘被丢弃。在当前的磁盘生产运行中模拟不期望的粗糙度的火山口形凸起具有在10至25μm的范围内的直径和在校准盘的标称表面上的高度hr在75至120nm范围内的周边脊。可以通过在校准盘的相同位置上照射激光能量的两个或更多个脉冲来实现具有该配置的紧公差凹坑形状的凸块。通过增加脉冲数，周边脊的高度逐渐增加。通过采用多个脉冲，周边脊的高度增加，而凹坑形凸起的直径基本保持不变。此外，通过使用多个脉冲，可以在5〜20μm的直径范围内和2〜120nm的高度范围内产生具有紧密公差的凹坑形凸起的高度。提供校准盘上的凹坑形突起的不同布置，用于增加PZT滑块的校准范围。
