Abstract
The invention discloses an apparatus and method for passive damping of slider modes in a storage device. An exemplary apparatus comprises a cradle for supporting a slider and comprising two side members and a center member, where each of the side members are disposed at opposite ends of the center member, and a viscoelastic layer lining two side members and the center member of the cradle.
Claims27
An apparatus for passive damping of slider modes in a storage device, comprising:
- a cradle for supporting a slider and comprising two side members and a center member where each of the side members are disposed at opposite ends of the center member;
- and
- a viscoelastic layer lining the two side members and the center member of the cradle.
12 The apparatus of claim 11, wherein the dimple on the load beam defines a pivot for pitch and roll movement of the slider.
A method for passive damping of slider modes in a storage device, comprising:
- providing a cradle comprising two side members and a center member where each of the side members are disposed at opposite ends of the center member;
- providing a viscoelastic layer;
- and
- supporting the slider in the cradle on the viscoelastic layer lining the two side members and the center member of the cradle.
24 The method of claim 23, wherein the dimple on the load beam defines a pivot for pitch and roll movement of the slider.
