摘要： Systems and methods are provided for burnishing a recording head in-situ in a magnetic recording disk drive. The burnishing process generates a tribocurrent, which is electricity generated by the rubbing of dissimilar materials. Different materials exhibit widely different tribocurrent characteristics while in sliding contact. The tribocurrent thus acts as an indicator of the particular materials of the recording head making contact with the magnetic recording media during different stages of the burnishing process. The tribocurrent is thus monitored to determine when it reaches a threshold value. The threshold value indicates that the burnishing has exposed a particular material of the recording head. Thus, the burnishing process may be stopped upon the tribocurrent reaching the threshold value so that the read sensor of the recording head is not burnished and inadvertently damaged.

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.
