ABSTRACT:
A floating head slider has a pair of side rails and a central rail on a air bearing surface thereof. Each of the side rails has a first, leading region extending parallel to the longitudinal axis of the slider, a second, intermediate region extending from the first region and deviating from the direction of the longitudinal axis toward the other of the side rails, and a third, trailing region extending from the second region and further deviating from the direction of the first region. The directions of the first, second and third regions correspond to the direction of the air flow at the innermost track, intermediate track and the outermost track, to provide constant floating height and reduced roll. The central rail has a neck between a leading, small width region and a trailing, increasing width region.
