摘要： A burnishing head configured to provide extremely close control of the burnishing height, to aerodynamically eject particles generated by the burnishing process from beneath the burnishing head onto the disc surface, whence they can be swept from the disc by centripetal force, and to optimize the tribological relationship between the burnishing head and a disc being burnished. The burnishing head includes a plurality of burnishing pads arranged in an elliptical pattern, with the actual burnishing surface of the burnishing pads being either ion milled to provide a closely controlled surface texture, or lapped to a extremely smooth surface. The shape of the individual burnishing pads is also formed by the process of ion milling, and is either elliptical, or, preferably, an aerodynamic teardrop shape, which acts to aerodynamically displace generated particles from beneath the burnishing head. The burnishing surface of the burnishing pads is coated with a diamond-like coating to improve the tribological relationship between the burnishing head and the disc.

摘要： A glide head with a slider body that has a leading edge, a trailing edge and an air bearing surface is disclosed. The glide head also has an array of thermal proximity sensing elements connected in a bridge circuit that are adjacent both the trailing edge and the air bearing surface, a heating element mounted to the glide body for elevating the temperature of the thermal proximity sensing elements in relation to the temperature of an inspected surface, and a controller coupled to the array of thermal proximity sensing elements. The controller receives signals from the thermal proximity sensing elements, and determines the existence of a surface variation in the inspected surface based upon differences in the signals received from the thermal proximity sensing elements.

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.
