摘要： Approaches for desiccant device within an enclosure protecting sensitive electronic equipment. Electronic equipment, such as a hard-disk drive (HDD), may comprise a desiccant device that possesses a water vapor permeability rate that matches or is substantially similar to the water vapor permeability rate of the enclosure. In this way, desiccant devices may prevent the desiccant material enclosed within from releasing large amounts of humidity into the interior of the electronic equipment.

摘要： Cleaning or polishing magnetic recording media (MRM) may comprise mounting and rotating the MRM on a spindle; circulating a tape adjacent to a surface of the MRM; and applying an electrostatic (ES) voltage to the tape and attracting particles located on the MRM to the tape. The ES voltage may apply an ES load to the tape to force the tape into contact with the surface of the MRM. No mechanical load may be applied to the tape to force the tape into contact with the surface of the MRM. Additionally, a mechanical load may be applied to the tape to force the tape into contact with the surface of the MRM.

摘要： A system and associated methods are described for preparing a magnetic disk for installation within a disk drive system. For example, a polyfunctional lubricant may be mixed with a chemical agent to esterify the polyfunctional lubricant and cap hydroxyl groups of the polyfunctional lubricant. The magnetic disk may then be dip coated with the polyfunctional lubricant and chemical agent mixture. A polishing system then polishes the magnetic disk via an abrasive polishing tape after dip coating the magnetic disk. A portion of the chemical agent is then removed from the magnetic disk to bond a portion of the lubricant to the magnetic disk to prevent the lubricant from interfering with a read/write head when installed within a disk drive system.

摘要： A disk drive having a layer of lubricant on a disk surface, where an undesirable lubricant layer thickness modulation is reduced by varying ω/f during operation of the disk drive. Here ω is the angular velocity of the disk and f is a resonant frequency of a head assembly containing the head. In this manner, the amplitude of the lubricant thickness modulation is decreased, improving disk drive performance. The ratio ω/f is preferably varied by varying the disk angular velocity ω.

摘要： A magnetic data storage medium includes a dedicated transducing head contact zone for engaging an air bearing slider, primarily when the disk is stationary. The contact zone is textured with an irregular sequence of spaced apart nodules forming a substantially circumferential, spiral path. The spiral path includes multiple terms that define a uniform radial pitch. The circumferential pitch is irregular, more preferably determined according to pseudo-random function in which the actual spacing intervals vary about a nominal interval, over a range comparable to, but generally less than, the interval. The pseudo-random array can be formed by a texturing process that includes directing a focused laser beam onto the contact zone. The disk is rotated to maintain a constant circumferential speed relative to the laser, and also is translated radially to provide the desired radial pitch. The laser is operated in a continuous wave mode, with an acousto-optic modulator between the laser and disk operated to provide a pseudo-random variance in time intervals between successive laser exposures.

摘要： A method for manufacturing a magnetic media having an extremely thin lubricant layer on a magnetic media. The thin lubricant layer decreases magnetic spacing to maximize magnetic performance of the magnetic data recording system. The lubricant layer is formed by first depositing a lubricant that includes two different lubricant materials, one bonded and the other non-bonded. After lubricant deposition a burnishing process can be performed, with the lubricant being thick enough for effective burnishing. Then, the disk is exposed to a solvent vapor, which removes most of the lubricant leaving only a very thin layer of the bonded lubricant material.
