摘要： A novel head includes an air bearing surface having a trailing pad adjacent the read transducer and lying in a primary plane. The air bearing surface includes a sub-ambient pressure cavity recessed from the primary plane by at least 500 nm. At least one leading pad is disposed upstream of the sub-ambient pressure cavity and has a leading pad surface in the primary plane. A moat is disposed upstream of the leading pad and is recessed from the primary plane by at least 500 nm. The moat continuously spans the entire width of the slider. A particle fence in the primary plane is disposed immediately upstream of the moat and adjacent the leading face. The particle fence continuously laterally spans at least 70% of the width of the slider.

摘要： Plural carbon-containing overcoats are formed on a media-facing surface of an information storage system head. The plural carbon-containing overcoats can mitigate corrosion without increasing head-media spacing. A first of the overcoats may be formed prior to creation of contact or air bearing features on the media-facing surface, with a second overcoat formed after creation of air bearing features. The first overcoat may be etched back substantially or completely prior to formation of the second overcoat. Laminated carbon-containing overcoats may have greater strength and/or coverage than non-laminated overcoats of the same thickness. The overcoats may be formed of several forms of diamond-like carbon (DLC) or silicon-carbide (SiC).

摘要： A head for use in a magnetic hard disk drive or other information storage device includes a novel ABS. The novel ABS includes an inter-cavity dam that is disposed between at least a portion of a cavity and a trailing pad. The inter-cavity dam is spaced longitudinally from the trailing pad by at least one thirtieth of the slider length. The inter-cavity dam includes an OD dam surface and an ID dam surface, with a slider-bisecting longitudinal plane passing between a majority of the OD dam surface and a majority of the ID dam surface. The OD dam surface is recessed from the first plane by an OD dam recession, and the ID dam surface is recessed from the first plane by an ID dam recession that is not equal to the OD dam recession.

摘要： A novel air bearing can be used in a magnetic hard disk drive or other information storage device. The novel air bearing includes a central cavity having a bottom surface, a leading pad adjacent to the central cavity, a trailing center pad having a top surface, and two inter-projection step regions. The trailing center pad has an aft region adjacent to the transducer and three projections extending from the aft region towards the central cavity. The central cavity separates the three projections from the leading pad. Each of the two inter-projection step regions lies at least partially between the projections, and each includes a surface at an intermediate level between a level of the top surface and the level of the bottom surface. The novel air bearing may be adequately insensitive to one or more factors affecting flying height variation in a micro-drive utilizing ramp load/unload of the slider.

摘要： A head has an air bearing surface with left and right leading pressurizing steps. The left and right leading pressurizing steps are each partially surrounded by left and right leading pads, respectively. The left leading pressurizing step includes a left short region that extends for a first distance (measured parallel to the slider longitudinal axis) from the leading face of the slider to the left leading pad. The left leading pressurizing step also includes a left long region that extends for a second distance (measured parallel to the longitudinal axis) from the leading face to the left leading pad. The second distance is at least 25% greater than the first distance. The left short region is disposed closer to the left lateral face than is the left long region. The left long region is disposed closer to the longitudinal axis than is the left short region.
