Abstract
A disk drive includes a drive housing and a storage disk rotatably coupled to the drive housing. In one embodiment, the storage disk includes a first substrate, a spaced-apart second substrate, a damping layer and a rigid substrate spacer. The first substrate is formed from a first material having a first composition and the second substrate is formed from a second material having a second composition. The damping layer is positioned at least partially between the first substrate and the second substrate. The rigid substrate spacer is positioned at least partially between the first substrate and the second substrate, and is formed from a third material having a third composition that is different from the first composition and the second composition. In one embodiment, the first composition is different than the second composition. The first substrate has a first thickness and the second substrate has a second thickness that can be different than the second thickness. In another embodiment, the disk drive includes a disk clamp having an upper portion and a lower portion. The rigid substrate spacer can be at least partially positioned directly between the upper and lower portions.
