Abstract
A disk drive is provided having a dynamic flying height or touch down power profile that is substantially flat across its stroke along the radius of a recording medium. At least two air-channeling elements are provided in a slider of the disk drive, that with the read/write head, flies above a surface of the recording medium. At an inner diameter and an outer diameter of the recording medium, the at least two air-channeling elements direct incoming air flow to an air bearing space defined by a bottom surface of the slider and the surface of the recording medium, increasing the flying height of the slider/read/write head at the inner diameter and outer diameter of the recording medium, thereby negating the effect of a middle diameter flying height hump of the recording medium.
