Abstract
A slider operating air bearing surface (ABS) to remove a front saturation water vapor pressure peak near a front bulwark and a bad flow pattern area the between front bulwark and a central island. The ABS implementing these operations. Alternatively, ABS includes a front bulwark channel in the front bulwark and a central fin between the front bulwark and the central island. Slider includes an embodiment of the ABS. Head gimbal assembly (HGA) includes the slider. Head stack assembly includes at least one HGA. Hard disk drive includes the head stack assembly. Manufacturing methods for the slider, the HGA, the head stack assembly, the hard disk drive, and these items as products of their manufacturing processes.
