Abstract:
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.
