Abstract
Disclosed herein are slider designs having improved trailing air flow dams, and data storage devices including such sliders. In some embodiments, a slider comprises a trailing edge and an air-bearing surface (ABS) comprising a trailing edge pad, and a trailing air flow dam coupled to the trailing edge pad, wherein, in an ABS view of the slider, the trailing air flow dam is recessed from and curves away from the trailing edge. In the ABS view, a shape of the trailing air flow dam may comprise two segments. The slider also has a leading edge and may at least one sub-ambient pressure cavity adjacent to the trailing air flow dam and disposed between the trailing air flow dam and the leading edge. A contact point of the trailing air flow dam may be at least 50 microns from a corner of the slider.
