Air bearing design to mitigate lube waterfall effect
View Patent ↗A slider comprises a slider trailing edge; a lubricant blocker having a disk facing surface and a lubricant blocker trailing edge, the lubricant blocker trailing edge having a lateral end trailing a central end; and a lubricant guiding channel recessed from the disk facing surface and extending from the slider trailing edge to the lubricant blocker trailing edge.
1. A slider, comprising:
a slider trailing edge;
a lubricant blocker having a disk facing surface and a lubricant blocker trailing edge, the lubricant blocker trailing edge having a lateral end trailing a central end; and
a lubricant guiding channel recessed from the disk facing surface and extending from the slider trailing edge to the lubricant blocker trailing edge;
wherein the lubricant blocker has a lubricant blocker leading edge, the lubricant blocker leading edge having a leading edge lateral end trailing a leading edge central end;
wherein, at the leading edge central end, the lubricant blocker leading edge is angled between 1° and 75° with respect to a line parallel to the slider trailing edge.
2. The slider of claim 1 , further comprising:
a second lubricant blocker having a second disk facing surface and a second lubricant blocker trailing edge, the second lubricant blocker trailing edge having a second lateral end trailing a second central end; and
a second lubricant guiding channel recessed from the second disk facing surface and extending from the slider trailing edge to the second lubricant blocker trailing edge.
3. The slider of claim 2 , wherein the first lubricant blocker and the second lubricant blocker are symmetrically disposed about a central axis of the slider.
4. The slider of claim 1 , wherein the central end is adjacent to a transducer region of the slider.
5. The slider of claim 1 , wherein the central end is adjacent to a center trailing pad of the slider.
6. The slider of claim 1 , wherein at the lateral end, the lubricant blocker trailing edge is angled between 1° and 45° with respect to a line parallel to the slider trailing edge.
7. A slider, comprising:
an air bearing surface;
an air bearing surface center trailing edge; and
a means for directing lubricant away from the air bearing surface central trailing edge while the slider is flying;
wherein the means for directing lubricant away from the air bearing surface central trailing edge while the slider is flying comprises a lubricant blocker having a lubricant blocker leading edge, the lubricant blocker leading edge having a leading edge lateral end trailing a leading edge central end;
wherein, at the leading edge central end, the lubricant blocker leading edge is angled between 1° and 75° with respect to a line parallel to the slider trailing edge.
8. The slider of claim 7 , wherein the means for directing lubricant away from the air bearing surface central trailing edge while the slider is flying further comprises a lubricant blocker trailing edge having a lateral end trailing a central end.
9. The slider of claim 8 , wherein the central end is adjacent to a transducer region of the slider.
10. The slider of claim 8 , wherein the central end is adjacent to a center trailing pad of the slider.
11. The slider of claim 7 , wherein the means for directing lubricant away from the air bearing surface central trailing edge while the slider is flying further comprises a lubricant guiding channel.
