    摘要： 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 being burnished. The burnishing head includes one or more spacer pads, associated with selected ones of the burnishing pads on the burnishing head, which remain in contact with the surface of a disc being burnished. The height from the contact surface of the spacer pad to the contact surface of the burnishing pad determines the effective burnishing height. The burnishing head also includes moats, or recessed areas, surrounding the burnishing pads to minimize the stiction caused by generation of a liquid meniscus between the disc and contacting elements of the burnishing head, and which act as collection points for particulates generated by the burnishing process. The spacer pads preferably include microtextured contact surfaces to minimize stiction and wear and further include a diamond-like carbon coating to further improve wear characteristics.

    摘要： An apparatus and associated method for constructing an abrading tool having a desired surface texture for a lapping surface of the tool. The abrading tool has a platen defining an external surface and a cavity intersecting the external surface. An adhesive is disposed in the cavity. An abrasive member is adhered at a proximal end thereof to the platen in the cavity by the adhesive so that the abrasive member extends beyond the external surface at a distal end thereof to define the lapping surface.

    摘要： A method of forming a tunneling magnetoresistive head begins by forming a tunneling magnetoresistive stack having a tunnel barrier. An air bearing surface is formed of the tunneling magnetoresistive stack. The air bearing surface is ion etched causing a deficiency of a constituent in a portion of the tunnel barrier adjacent the air bearing surface. The deficiency of the constituent is replenished in the portion of the tunnel barrier adjacent the air bearing surface to restore the electrical properties of the tunnel barrier.
