Abstract
In accordance with this invention, an air bearing slider has a mounting side which has a relieved portion formed by a stepped-contour or a tapered contour. The stepped-contour includes an adherent surface adjacent the rear face of the air bearing slider and a notch surface adjacent the front face of the air bearing slider. The notch surface is closer to the air bearing surface than the adherent surface. The tapered contour includes an adherent surface adjacent the rear face and a taper surface adjacent the front face such that the taper surface is at an angle to the adherent surface. The clearance provided by the relieved portion eliminates interference between the air bearing slider and the load beam surround portions which support the air bearing slider. Depth of the relieved portion of the air bearing slider can be altered easily during grinding for customized multiple drive designs without major retooling effort. To eliminate any potential contact between the corners of the adherent surface of the air bearing slider and the load beam surround portions, cutouts and/or etched regions are provided to the load beam surround portions adjacent to the adherent surface. The relieved po…
