摘要： A disc head slider includes a leading slider edge, a cavity dam, a subambient pressure cavity, which trails the cavity dam and has a cavity floor, and first and second rails disposed about the subambient pressure cavity. Each rail has leading and trailing bearing surfaces and a recessed surface extending between the leading and trailing bearing surfaces, which is recessed from the bearing surfaces and raised from the cavity floor, across the rail width. Recessed leading channels are positioned near the leading slider edge and have a leading channel end open to fluid flow from the leading slider edge, non-divergent channel side walls, and a trailing channel end closed to the fluid flow. A trailing channel is recessed within each of the trailing bearing surfaces and has a leading channel end open to fluid flow from the respective recessed surface, non-divergent channel side walls, and a trailing channel end closed to the fluid flow.

摘要： A disc head slider for supporting a transducer relative to a data storage disc includes a slider body having a disc-facing surface with a leading slider edge and a trailing slider edge. First and second rails are disposed on the disc-facing surface about a central recess and form first and second bearing surfaces, respectively, which terminate prior to the trailing slider edge. First and second wear-resistant pads are formed on the disc-facing surface between respective ones of the first and second bearing surfaces and the trailing slider edge. The first and second wear-resistant pads are raised from the central recess and are recessed from the first and second bearing surfaces to provide transitions in the disc-facing surface that generate vibration-dampening pressure gradients while limiting contact between the pads and the data storage disc during operation.

摘要： A data storage system including a disc for storing digital information and transducer for retrieving such information. A slider supports a transducers proximate the disc surface and includes a bearing surface generally facing the disc surface for operation of the transducer above the disc surface. The bearing includes raised bearing surfaces, and shock-absorbing pads which are spaced from a base surface and extend to an elevation aligned with or below the bearing surfaces. Shock pads are located to provide a contact interface between the slider and disc surface.

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. For example, the pads may be used to reduce the stiction or improve flying characteristics. Flying instabilities associated with the pads are addressed by a number of characteristics provided to the air bearing surface.

摘要： The present invention includes the realization that air bearing surface (ABS) microtexturing (i.e., the production of well-defined texture patterns on an ABS) affords an effective method to control the size of the apparent area of contact during head-to-disc frictional interaction, and thus provides a method to effectively prevent excessive friction force build-up which can lead to catastrophic tribological failure (head crash) during the glide characterization of super-smooth media for high areal density (for example greater than 20 Gb/in2) head-to-disc interfaces (ADIs).

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.
