    摘要: An air bearing slider for use in carrying a transducer adjacent a recording medium exhibits reduced sensitivity to variations in roll, crown, and skew. In one embodiment, the slider comprises an air bearing slider having a pair of substantially coplanar side rails disposed along the sides of the air bearing surface so as to form a recessed section between the side rails. The recessed section is open at both the leading and trailing ends of the slider while each side rail has a tapered section or etched step at the leading edge of the slider. One rail carries the transducer and extends for the entire length of the slider body. The rail without a transducer extends from the leading edge toward the trailing edge, but does not extend all the way to the trailing edge. Under some skew, accessing, and crash stop impact conditions, the resulting slider roll causes the flying height of the inactive rail to drop. By proper selection of the length and width of the inactive rail, the roll is biased such that the fly height of the inactive rail remains higher than that of the active rail even under worst case conditions. Therefore, minimum slider to disk spacing is larger than it would be for a slider design in which all rails extend the entire length of the slider.

    摘要: An air bearing slider for supporting a magnetic transducer comprising a pair of coplanar side rails on the sides of an air bearing surface of the slider and a center rail along the central region of the air bearing surface to form recessed areas between the rails which extend from the leading to the trailing end of the slider. All the rails have a tapered section at their leading ends. The side rails have a width that does not exceed the width of the side rails at the leading end, and the side rails extend only part way to the trailing end of the slider. The width of the center rail is small at the leading end and greatest at the trailing end of the slider, where the transducer is supported.
