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.

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.

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.

A slider having contact protection for ultra-low fly heights. The contact protection includes contact pads having an ultra-low height dimension to reduce friction and damage for intermittent contact for ultra-low fly height applications.

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).

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.

A slider is used for supporting a transducing head proximate a rotating disc. The slider includes a slider body having a disc opposing face bounded by a leading edge, a trailing edge, and first and second side edges. The slider body has a longitudinal axis. An air bearing surface is defined on the disc opposing face and the air bearing surface has a pad proximate the trailing edge. A trench is positioned adjacent to the pad with the trench being recessed from the air bearing surface at a step depth. A channel for flushing lubricant from the disc opposing face is positioned on the pad. The channel is recessed from the air bearing surface at a channel depth.

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.
