Low sway space isolation chassis adapter for a disc drive

A low sway space isolation chassis adapter is disclosed to facilitate the mounting of a disc drive in a mounting environment, the disc drive having a base deck to which a printed circuit board is affixed. A mounting plate is secured to mounting features of the base deck so that the printed circuit board is disposed between the mounting plate and the base deck. The mounting plate includes a central web to which a damping layer is affixed. A chassis plate is disposed between the mounting plate and the printed circuit board, the chassis plate having a central web which is affixed to the damping layer and mounting flanges facilitating the mounting of the disc drive. The damping layer and the central webs of the chassis plate and mounting plate form a laminate which provides constraint layer damping for the disc drive.
