Abstract: A crash stop for an actuator arm of a hard disk drive includes a support body having a cylindrical form and a central axis; and a cantilever element joined at a proximal portion to the support body and having a distal portion spaced apart from the support body to allow for deflection of the distal portion of the cantilever element or the support body relative to the other.

Abstract: Methods and apparatus for transferring heat according to various aspects of the present invention operate in conjunction with a heat source on a substrate. In one embodiment, a lid is adapted to engage the substrate. The lid may comprise a thermally conductive rigid body and one or more hardstops configured to limit a bond line distance between the rigid body and the heat source. A thermal interface material may be disposed in the bond line between the heat source and the lid. The thermal interface material may be adapted to provide a thermally conductive adhesive bond between the lid and the heat source.
