Slider with leading edge blend and conformal step features
View Patent ↗A method of forming a slider includes forming a leading edge blend on a leading edge of the slider. After the leading edge blend is formed, the method further includes forming at least one step feature conformal to the leading edge blend. A slider having an air bearing surface includes a leading edge blend and at least one step feature conformal to the leading edge blend.
1. A method of forming a slider, comprising:
forming a leading edge blend on a leading edge of the slider; and
after the leading edge blend is formed, forming at least one step feature conformal to the leading edge blend,
wherein the step feature is formed by etching the leading edge blend.
2. The method of claim 1 further comprising forming a carbon overcoat on the slider after the leading edge blend is formed.
3. The method of claim 1 , wherein the step of forming the leading edge blend comprising abrading the slider with an abrasive surface.
4. The method of claim 3 , wherein the abrasive surface is placed at an angle to the air bearing surface while abrading the slider.
5. The method of claim 4 , wherein the angle is between 10 and 20 degrees.
6. The method of claim 3 , wherein a compliant material is placed behind the abrasive surface during the abrading of the slider.
7. The method of claim 6 , wherein the compliant material has a durometer hardness greater than 40 Shore D.
8. The method of claim 3 , further comprising vibrating the abrasive surface.
9. The method of claim 1 , further comprising forming a trailing edge blend on a trailing edge of the slider.
10. The method of claim 1 , further comprising forming a blend on at least one side of the slider.
