  • Disk-drive chassis for reducing transmission of vibrations between disk-drive units of a disk-drive array
    Patent number: 6154361
    Abstract: A disk-drive chassis of the invention has stiffening and damping members for reducing the transmission of vibrations between disk-drive units of a disk-drive array. The stiffening members include vertical dividers that are mechanically coupled between top and middle panels of the chassis. The stiffening members also include a corrugated stiffener attached to a bottom surface of the middle panel. The stiffener's corrugations are aligned parallel with a spindle axis of the respective disk-drive units. The damping member includes a constrained-layer damping plate which is attached to a top surface of the top panel by a visco-elastic damping adhesive. The chassis allows improved performance by the individual disk-drive units.
