Abstract:
A slider resistant to lubricant accumulation. The slider resistant to lubricant accumulation includes a positive-air-pressure portion of the slider configured to levitate the slider above a magnetic-recording disk and a negative-air-pressure portion of the slider configured to bring the slider into proximity with the magnetic-recording disk at a fly height sufficient for writing data to and reading data from the magnetic-recording disk. The slider resistant to lubricant accumulation also includes a lubricant-accumulation barrier disposed in proximity to a trailing edge of the slider. The lubricant-accumulation barrier is configured to reduce lubricant accumulation on the slider. The lubricant-accumulation barrier also includes a plurality of lubricant-accumulation-barrier portions disposed at a plurality of respective depths below an outer-most surface of a disk-facing side of the slider.
