Patent ID: 8174794

Claim:
A slider resistant to lubricant accumulation, comprising: a positive-air-pressure portion of said slider configured to levitate said slider above a magnetic-recording disk; a negative-air-pressure portion of said slider configured to bring said slider into proximity with said magnetic-recording disk at a fly height sufficient for writing data to and reading data from said magnetic-recording disk; and a lubricant-accumulation barrier disposed in proximity to a trailing edge of said slider, said lubricant-accumulation barrier configured to reduce lubricant accumulation on said slider and comprising; a first lubricant-accumulation-barrier portion; and a second lubricant-accumulation-barrier portion, wherein said second lubricant-accumulation barrier portion is discontinuous from an outside-diameter side of said slider to an inside-diameter side of said slider; wherein said first lubricant-accumulation-barrier portion is disposed closer to said trailing edge of said slider than said second lubricant-accumulation-barrier portion over a portion of said slider proximate to a trailing-edge center pad of said slider, said second lubricant-accumulation-barrier portion is disposed closer to said trailing edge of said slider over at least some portion of said slider whereat said first lubricant-accumulation-barrier portion is not disposed and wherein said first lubricant-accumulation-barrier portion and said second lubricant-accumulation-barrier portion are disposed at a plurality of respective depths below an outer-most surface of a disk-facing side of said slider.
