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.

摘要： A disc head slider includes a cavity dam, a subambient pressure cavity and first and second elongated rails. The first and second rails are disposed about the subambient pressure cavity. Each of the rails has a rail width measured from an inner rail edge to an outer rail edge, a leading bearing surface, a trailing bearing surface, and a recessed area extending between the leading and trailing bearing surfaces. The recessed area is recessed from the bearing surfaces and raised from the cavity floor, across the rail width. First and second convergent channels are recessed within the trailing bearing surfaces of the first and second rails, respectively. Each channel has 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： According to one embodiment of the present invention, a fly height of a read/write head in a disc drive is actively controlled as the read/write head is positioned over a rotating disc with a patterned media. The patterned media includes ridges and grooves in servo wedges in the patterned media. According to another embodiment of the present invention, an estimated fly height of the read/write head is compared with a desired fly height to generate a control signal. The control signal is used to apply a voltage difference across a piezoelectric layer joining the read/write head to a slider to move the read/write head relative to the slider and adjust the fly height of the read/write head. According to another embodiment of the present invention, a map of ridges and grooves in the patterned media is generated and the fly height of the read/write head is actively controlled based on information in the map.
