Number	Title	Issue Date
6790133	Suspension assembly for magnetic disk glide and burnish applications A glide/burnish suspension assembly processes magnetic memory storage disks by “flying” a glide/burnish slider across the surface of a rotating disk. A glide/burnish suspension assembly as described herein includes mounting holes and a tooling hole that are comp...	09/14/2004
6419551	High speed burnishing of asperities in a disk drive A method of burnishing an asperity on a magnetic surface of an operational disk drive. The disk drive includes a slider maintaining an MR element. Rotation of the disk relative to the slider forms an air bearing between the slider and the disk surface, ge...	07/16/2002
6296552	Burnishing head with fly height control spacer A burnishing head configured to provide extremely close control of the burnishing height, to minimize stiction between the burnishing head and a disc being burnished, and to optimize the tribological relationship between the burnishing head and a disc bei...	10/02/2001
5782680	Burnishing head for polishing surfaces of carriers of magnetic media A burnishing head, which is used to polish the surface of carriers that hold magnetic media (e.g., disks for computer hard drives), includes a slider that is mounted on a suspension. The slider includes at least four protrusions that protrude toward the s...	07/21/1998
