Reducing slider bounce in a hard disk drive

1. A device for reducing slider bounce, said device comprising:

a first material forming a single protrusion from and coupled with a slider body of a hard disk drive at a non-recessed location of said slider body, said first material comprising a portion that is flexible in a first direction and is substantially non-flexible in a second direction, wherein said first material reduces said slider bounce while said first material is directly or indirectly in contact with a disk of said disk drive by substantially absorbing forces associated with interaction between said slider and said disk, wherein said first direction is a vertical direction, said vertical direction being a direction that is normal to said disk, wherein said second direction is a horizontal direction, said horizontal direction being a direction that is parallel to a surface of said disk, wherein said portion of said first material that is non-flexible in said second direction is stiffer than said portion that is flexible in said first direction; and

a second material coupled with a disk-facing side of said first material, said second material configured for making contact with said disk, wherein said second material is of a same composition as said slider and is non-flexible in said vertical direction;

a first set of one or more electrodes coupled with said first material; and

a second set of one or more electrodes coupled with said first set of one or more electrodes and coupled with said slider, wherein said slider may cause a change in voltage between said first set of one or more electrodes and said second set of one or more electrodes, thereby effecting a changed distance between said first material and said disk.

2. The device of claim 1 , wherein said second material is alumina.

3. The device of claim 2 , further comprising a carbon overcoat.

4. The device of claim 1 , wherein said second material is spherically-shaped.

5. A slider assembly used in a disk drive for reducing slider bounce, said slider assembly comprising:

a slider;

a first material forming a single protrusion from and coupled with a disk-facing portion of said slider at a non-recessed location of said disk-facing portion, said first material comprising a portion that is flexible in a first direction and is substantially non-flexible in a second direction, wherein said first material reduces said slider bounce while said first material is directly or indirectly in contact with a disk of said disk drive by substantially absorbing forces associated with interaction between said slider and said disk, wherein said first direction is a vertical direction, said vertical direction being a direction that is normal to said disk, wherein said second direction is a horizontal direction, said horizontal direction being a direction that is parallel to a surface of said disk, wherein said portion of said first material that is non-flexible in said second direction is stiffer than said portion that is flexible in said first direction;

a second material coupled with a disk-facing side of said first material, said second material configured for making contact with said disk, wherein said second material is of a same composition as said slider and is non-flexible in said vertical direction;

a first set of one or more electrodes coupled with said first material; and

a second set of one or more electrodes coupled with said first set of one or more electrodes and coupled with said slider, wherein said slider may cause a change in voltage between said first set of one or more electrodes and said second set of one or more electrodes, thereby effecting a changed distance between said first material and said disk.

6. The slider assembly of claim 5 , further comprising:

a first attachment comprising a first end and a second end, said first end coupled with a suspension and said second end coupled with a non-disk facing portion of said slider, wherein said first attachment is configured to flexibly carry said slider at said second end while remaining coupled with said suspension at said first end, thereby reducing said slider bounce by absorbing a portion of said forces associated with interaction between said slider and said disk.

7. The slider assembly of claim 6 , wherein said first attachment is a cantilever.

8. The slider assembly of claim 5 , wherein said second material is alumina with a carbon overcoat.

9. The slider assembly of claim 5 , wherein said second material is spherically-shaped.
