摘要： A contaminant reduction system is shown for a disk drive assembly having a closed interior and slider disk components located therein which would be adversely affected by condensed volatiles generated within the assembly. A Peltier element is located within the closed interior of the disk drive assembly so as to condense volatiles present within the interior at a desired condensation point within the closed interior. A getter material, such as a microporous sintered alumina, is located within the closed interior of the disk drive assembly at the condensation point for permanently trapping and maintaining condensed volatiles which are condensed by the Peltier element.

摘要： The invention relates to an improved high performance magnetic recording device. The recording device comprises a magnetic recording disk, a slider having a transducer for reading or writing data on the disk, a motor operable to rotate the disk at speeds greater than 7000 RPM and an actuator connected to the slider to move the slider across the disk. The trailing surface of the slider is coated with a low surface energy film to prevent build up of droplets of liquid contaminants.

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 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： Embodiments of the present invention pertain to reducing the obstruction of air flow through a bypass channel associated with a disk drive. According to one embodiment, disk drive filtering system includes a selective filtering region, an electrostatic pass-by filter, and a filter free region. The selective filtering region is disposed within a bypass channel. The electrostatic pass-by filter is disposed within the selective filtering region and is used for filtering the air that flows through the selective filtering region. The filter free region is disposed proximate to the electrostatic pass-by filter so that a substantial portion of the air is allowed to flow unobstructed through the selective filtering region.

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.
