Claims
- 1. A slider for supporting a transducing head proximate a rotating disc, the slider comprising:
a slider body having a disc opposing face bounded by a leading edge and a trailing edge; and means for capturing contaminants on the slider body and expunging the contaminants towards the trailing edge of the slider body.
- 2. The slider of claim 1 wherein the means for capturing and expunging contaminants on the slider body comprises a furrow positioned on the disc opposing face.
- 3. A slider for supporting a transducing head proximate a rotating disc, the slider comprising:
a slider body having a disc opposing face bounded by a leading edge, a trailing edge and first and second side edges, the slider body having a longitudinal axis; an air bearing surface defined on the disc opposing face; and a furrow positioned on the disc opposing face for flushing contaminants towards the trailing edge of the slider body.
- 4. The slider of claim 3 wherein the furrow has a furrow depth of about 0.5 microns to about 1.0 microns.
- 5. The slider of claim 3, and further comprising a cavity positioned on the disc opposing face of the slider body and the cavity being recessed from the air bearing surface at a cavity depth.
- 6. The slider of claim 5 wherein the cavity depth is about 1.5 microns to about 3.0 microns.
- 7. The slider of claim 5 wherein the furrow is recessed from the cavity.
- 8. The slider of claim 3 wherein the furrow has a first end and a second end, the first and second ends lying adjacent the trailing edge of the slider body such that the furrow has a semi elliptical shape.
- 9. The slider of claim 8 wherein the furrow is centered about the longitudinal axis.
- 10. The slider of claim 3, and further comprising:
a first side arm and a second side arm extending from the furrow, the first side arm extending relative to the longitudinal axis at a positive angle greater than zero degrees and less than 90 degrees and the second side arm extending relative to the longitudinal axis at a negative angle greater than zero degrees and less than 90 degrees.
- 11. The slider of claim 3, and further comprising:
first and second side rails positioned substantially along the first and second side edges.
- 12. The slider of claim 11 wherein the first and second side rails are recessed from the air bearing surface at a step depth.
- 13. The slider of claim 12 wherein the step depth is about 0.1 microns to about 0.3 microns.
- 14. The slider of claim 12, and further comprising:
a first side furrow disposed in the first side rail, the first side furrow being recessed from the step depth at a side furrow depth and the first side furrow extending relative to the first side edge at a negative angle greater than zero degrees and less than 90 degrees; and a second side furrow disposed in the second side rail, the second side furrow being recessed from the step depth at the side furrow depth and the second side furrow extending relative to the second side edge at a positive angle greater than zero degrees and less than 90 degrees.
- 15. The slider of claim 14 wherein the side furrow depth is about 0.5 microns to about 1.0 microns.
- 16. The slider of claim 12, and further comprising:
a first side furrow disposed in the first side rail, the first side furrow being recessed from the step depth at a side furrow depth and the first side furrow extending relative to the longitudinal axis at a positive angle greater than zero degrees and less than 90 degrees; and a second side furrow disposed in the second side rail, the second side furrow being recessed from the step depth at the side furrow depth and the second side furrow extending relative to the longitudinal axis at a negative angle greater than zero degrees and less than 90 degrees.
- 17. The slider of claim 3 wherein the furrow has a width of at least about 20 microns.
- 18. A slider for supporting a transducing head proximate a rotating disc, the slider comprising:
a slider body having a disc opposing face bounded by a leading edge, a trailing edge and first and second side edges, the slider body having a longitudinal axis; an air bearing surface defined on the disc opposing face, the air bearing surface having at least one pad behind the leading edge; a cavity positioned on the disc opposing face, wherein the cavity is at a cavity depth recessed from the air bearing surface, at least a portion of the cavity preceding the pad; and a furrow for flushing contaminants towards the trailing edge of the slider body, the furrow positioned on the disc opposing face.
- 19. The slider of claim 18, and further comprising a first side arm and a second side arm extending from the furrow, the first side arm extending relative to the longitudinal axis at a positive angle greater than zero degrees and less than 90 degrees and the second side arm extending relative to the longitudinal axis at a negative angle greater than zero degrees and less than 90 degrees.
- 20. The slider of claim 18, and further comprising first and second side rails positioned substantially along the first and second side edges wherein the first and second side rails are recessed from the air bearing surface at a step depth.
- 21. The slide of claim 20, and further comprising a first side furrow disposed in the first side rail and a second side furrow disposed in the second side rail wherein the first and second side furrows are recessed from the step depth at a side furrow depth.
- 22. The slider of claim 21 wherein the first side furrow extends relative to the first side edge at a negative angle greater than zero degrees and less than 90 degrees and the second side furrow extends relative to second side edge at a positive angle greater than zero degrees and less than 90 degrees.
- 23. The slider of claim 21 wherein the first side furrow extends relative to the longitudinal axis at a positive angle greater than zero degrees and less than 90 degrees and the second side furrow extends relative to the longitudinal axis at a negative angle greater than zero degrees and less than 90 degrees.
