The ramp is positioned along an edge of the disc to engage a portion of the actuator when the actuator is in a parked position. The slider is supported over the disc by the actuator and includes first and second elongated rails. Each rail has a leading bearing surface, a trailing bearing surface, and a recessed area extending between the leading and trailing bearing surfaces. First and second convergent channels are recessed within the trailing bearing surfaces of the first and second rails, respectively. Each channel includes a leading channel end open to fluid flow from the respective recessed area, non-divergent channel side walls and a trailing channel end closed to the fluid flow and forward of a localized region of the respective trailing bearing surface.

摘要： A disc drive data storage system is disclosed that includes a disc storage medium having a disc surface. The system also includes an armature and a slider coupled to the armature. The slider supports a transducer head that communicates with the disc storage medium. The slider flies above the disc surface and positions the transducer head proximate the disc surface. Data representing a topography map of the disc surface is stored in a memory. A controller controls the fly height of the slider above the disc surface as a function of the topography map of the disc surface.

摘要： An air bearing slider for a disc drive has an overcoat localized on the air bearing surface to provide a continuous covering over a leading portion of the air bearing surface. The overcoat terminates in a trailing cut-off line, and a trailing portion of the air bearing surface is not covered by overcoat. The overcoat also covers the pole tips of the transducer at a pole tip recession from the air bearing surface. The leading portion covered by the overcoat includes all of the air bearing surface that contacts the disc during contact/start/stop, which is protected by a uniform continuous overcoat layer. The trailing cut-off line is disposed at an angle to expose the trailing corners of the air bearing surface, such that all of the overcoat is elevated above the lowermost portion of the air bearing surface through pitch and roll angles of flying at inner and outer radii. Methods of applying the localized overcoat include subtractive and additive photolithographic deposition processes. The overcoat over the pole tips protects the pole tips during subsequent processing steps of forming the slider cavity.

摘要： A disc storage system includes a rotating disc and a transducer. The transducer is carried on a slider which is supported by an armature. The armature is used to move the slider radially across the disc surface whereby information may be read from or written to the disc surface of the transducer. The slider includes an air bearing surface which faces the disc surface. As the disc rotates, the air bearing surface causes the slider to “fly” over the disc surface. Pads are provided on the air bearing surface to improve operational characteristics of the system and texturing is provided to a landing zone region on the disc surface.

摘要： A slider is provided for actively controlling a fly height of the slider relative to a data storage disc during operation of a data storage system. The slider includes a slider body having front and back surfaces, a length and a crown curvature on the front surface along the length. The slider also includes first and second elongated rails which are positioned on the front surface along the length of the slider body and form first and second bearing surfaces. Each bearing surface includes a leading portion, a trailing portion and a waist portion, wherein the waist portion is wider than the leading and trailing portions and has a maximum width within a middle half of the length of the slider body. A deformable material is positioned on the slider body having a dimension that is changeable in response to an electrical control signal applied in a deformable material, wherein a change in the dimension causes a change in the crown curvature.

摘要： A magnetic data transducing head slider is provided with a transversely extended crossbar or other barrier near the leading edge. The barrier is deposited onto the air bearing surface of the slider using photolithographic techniques that enable precise determination of the barrier dimensions and the barrier set-back from the leading edge. The barrier set-back, width and thickness can be selected to control the transducer flying height and the pitch of the slider relative to the data recording surface of a magnetic disk when the slider is aerodynamically supported relative to the disk. The barrier also acts as a shield to minimize particulate contamination.
