摘要： A disc drive includes a base and a disc rotatably attached to the base. The disc drive also includes an actuator assembly rotatably attached to said base and a device for moving the actuator assembly. The actuator assembly carries a slider. A slider for a disc drive adapted to interface with the surface of the disc. The surface of the disc is provided with an overcoat having a specific hardness. The slider has a leading edge, a trailing edge, and an air bearing surface positioned between the leading edge and the trailing edge. The slider includes a plurality of slider integrated pads, at least some of the slider integrated pads having a hardness which is greater than the hardness of the disc surface. All the slider integrated pads may be harder than the hardness of the disc surface or at least a group of slider integrated pads located near the trailing edge of the slider are harder than the hardness of the disc surface.

摘要： A disk drive system or information handling system includes a base, a disk stack rotatably attached to the base, and an actuator assembly movably attached to the base. An actuator assembly is movably attached to the base of the disk drive. The actuator assembly moves the load springs and attached slider and transducers to various radial positions on the disk. The slider is a block of material having a leading edge, a trailing edge, a first side rail, a second side rail, a leading tapered edge and a center island. The center island is positioned near the trailing edge and includes the read and write heads or transducer. Sliders have a backside surface and an air-bearing surface. The slider also has one or more pads positioned near the edges of the first rail, the second rail, and the leading tapered edge. The pads are positioned at least a selected distance from the trailing edge. The pads are also positioned such that they are unaligned in the sliding direction. The pads are also positioned so that they are unaligned in the sliding direction when the first side rail and the second side rail form an angle with respect to a tangent at the radial position on the disk. In other words, the pads are unaligned when the slider is skewed with respect to the disk. The pads are formed using photolithography techniques.

摘要： A disc head slider includes a slider body having a leading slider edge, a trailing slider edge, a bearing surface, a back surface, which is opposite to the bearing surface, and a length measured from the leading slider edge to the trailing slider edge. First and second discrete pads extend normally from the bearing surface. The first pad is located forward of a midpoint along the length, and the second pad is located rearward of the midpoint and forward of the slider trailing edge. A recess is formed in the back surface and has a recess floor, which defines a load point surface located between the first and second pads along the length.

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.
