A disc head slider (110, 450, 500, 700, 800) includes a slider body having a disc-opposing face (200) with leading and trailing slider edges (204 and 206, 452, 454, 502 and 504), a slider length measured between the leading and trailing slider edges, a bearing surface (202, 214, 262, 270, 272, 510, 524, 720, 726, 732, 820, 826, 832), a recessed area (240, 462, 518, 520, 710, 712, 810, 812) an inlet (200, 496, 532, 734, 834) and a convergent channel (264, 494, 532, 734, 834). The recessed area (240, 462, 518, 520,710, 712, 810, 812) is recessed from the bearing surface (202, 214, 262, 270, 272, 510, 524, 720, 726, 732, 820, 826, 832). The inlet (300, 496, 532, 734, 834) has a leading channel end, which is open to air flow from the leading slider edge (204, 452 and 502), channel side walls (304, 306, 498, 499, 538, 540) and a trailing channel end. The convergent channel (264, 494, 532, l734, 834) has a leading channel end (280, 534, 736,836), which is open to fluid flow from the inlet, channel side walls (284, 538, 540, 740, 742, 840, 842) and a trailing channel end (282, 536, 738, 838), which is closed to the fluid flow. The training channel end (282, 536, 738, 838) of the convergent channel is located along the slider length rearward of at least a portion of the recessed area (240, 462, 518, 520, 710, 810, 812) and forward of at least a portion of the portion of the bearing surface (262, 480, 524, 732, 832). |
