International Classification:

G11B 2121

US Classification:

3602358, 3602363, 360 9701

Abstract:

A disc drive assembly includes a housing, a disc, an actuator, a ramp and a slider. 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.

International Classification:

G11B 560

US Classification:

3602366, 3602369

Abstract:

A disc drive slider includes a slider body and a rail formed on the slider body. The rail includes a bearing surface which faces a surface of a disc. A textured portion is formed on the bearing surface of the rail. Pads are deposited on the textured portions. The pads operate to reduce stiction, dynamic friction, and the likelihood of damage to the slider or the surface of the disc due to contact therebetween.

International Classification:

G11B 1732

US Classification:

3602364, 360236, 3602362, 3602369, 3602356

Abstract:

An air bearing slider includes an asymmetric taper for control of pressurization and suction force formation. The asymmetric taper is disposed on an edge of a slider to accommodate for the speed differential across the disc radial direction, thereby improving take-off performance, reducing sensitivity to skew angle and altitude variation, and reducing the severity of impacts during ramp loading and unloading. A leading taper intersecting a leading surface and air bearing surface of the slider is asymmetric about a longitudinal, bisecting plane of the slider. In another embodiment, side taper intersecting a side surface and air bearing surface of the slider is asymmetric about a latitudinal, bisecting plane of the slider. In another embodiment, rail taper intersecting a rail recess surface and air bearing surface of the slider is asymmetric about a longitudinal, rail-bisecting plane.

US Classification:

3602365, 3602351, 3602357, 3602947

Abstract:

A head for a disc drive and a method of making the head. The head includes a substrate with a trailing side and a first air bearing surface that generates lift. A magnetic transducer is deposited along the trailing side and has a pole tip that is spaced apart from a disc by a pole-to-disc spacing. The head also includes a deposit along the trailing side. The deposit includes a second air bearing surface that changes position relative to the first air bearing surface as temperature increases.
