    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 method of processing media comprises bonding a high molecular weight first lubricant to media; loading and rotating the media in a burnishing device; applying a tape to the rotating media while applying a second lubricant to the tape, such that at least some of the second lubricant is transferred from the tape to the media; and evaporating substantially all of the second lubricant from the polished media within 24 hours. The second lubricant may comprise a low molecular weight, non-functional, free lubricant that does not bond with the media.

    摘要: In a method for negatively biasing a slider with respect to a disk to reduce slider wear and provide burnish rate control a negative bias voltage is generated between the slider and the disk surface respectively, the negative bias voltage causing slider/disk contact wear to occur on the disk instead of on the slider.

    摘要: A thin film magnetic disk overcoat for perpendicular magnetic recording media comprises three layers. The initial layer comprises a dense mixture of both SiCx and SiNy compounds. The intermediate layer is a relatively dense high energy carbon process and the outer layer is sputtered CNx. The overall thickness of the overcoat is less than about 35 Å. The overcoat has the desired lubricant interaction with the elements that comprise the magnetic layers adjacent to the overcoat. Adjusting the SiC/SiN ratio in the overcoat eliminates potential negative interaction with the magnetic layers of the disk.

    摘要: A polishing system and associated methods are described for polishing a magnetic disk used in a disk drive system. The polishing system includes a polishing film that is used to polish the magnetic disk. The polishing system also includes an actuator operable to move the polishing film across a surface of the magnetic disk to polish the magnetic disk. The polishing system also includes a pad having at least one protrusion extending from a surface of the pad. The protrusion is configured to contact the polishing film and press the polishing film against the magnetic disk. The protrusion is operable to compress to about the surface of the pad when in contact with the polishing film. Once polishing is complete, the pad retracts from the polishing film and the protrusion extends from the pad, reducing the adhesion force between the pad and the polishing film.

    摘要: Glide test systems and associated methods are described. A glide test system includes a glide test head that is flown over the surface of a recording disk to detect asperities on the recording disk. The glide test head includes a detection pad on the trailing end of the head. Heating elements are fabricated proximate to the detection pad. The heating elements are independently controllable to control the amount of protrusion of different regions of the detection pad. The heating elements thus provide a way to substantially flatten the detection surface of the detection pad, and compensate for an uneven topography on a detection surface.
