Abstract
Embodiments of the present invention include a head slider for a magnetic disk drive. The head slider comprises a first recess on the air bearing surface of the head slider. The head slider further comprises a second recess on the air bearing surface, wherein the first recess is deeper than the second recess and is closer to the leading edge than the second recess and wherein the second recess is closer to the trailing edge than the first recess.
Claims29
A head slider for a magnetic disk drive, said slider comprising a leading edge and a trailing edge of an air bearing surface, said head slider further comprising:
- a first recess on said air bearing surface of said head slider;
- and
- a second recess on said air bearing surface of said head slider wherein said first recess is deeper than said second recess and is closer to said leading edge than said second recess and wherein said second recess is closer to said trailing edge than said first recess.
A disk drive assembly comprising:
- a rotatable magnetic disk;
- and
- a head gimbal assembly coupled to an actuator, said head gimbal assembly comprising a head slider, said slider comprising:
- an air bearing surface comprising a leading edge and a trailing edge;
- a first recess on said air bearing surface of said head slider;
- and
- a second recess on said air bearing surface of said head slider wherein said first recess is deeper than said second recess and is closer to said leading edge than said second recess and wherein said second recess is closer to said trailing edge than said first recess.
A head gimbal assembly comprising a head slider for reducing fly height loss at altitude and for increasing shock protection, said head slider comprising:
- an air bearing surface comprising a leading edge and a trailing edge;
- a first recess on said air bearing surface of said head slider;
- and
- a second recess on said air bearing surface of said head slider wherein said first recess is deeper than said second recess and is closer to said leading edge than said second recess and wherein said second recess is closer to said trailing edge than said first recess.
