    Abstract: A base mechanism for use in a multi-chip module (MCM) is described. This base mechanism includes a substrate having top and bottom surfaces. The bottom surface includes first electrical connectors that convey power, and through-substrate vias (TSVs) between the top and bottom surfaces are electrically coupled to these electrical connectors. Furthermore, a bridge chip is rigidly mechanically coupled to the top surface. This bridge chip includes proximity communication connectors that communicate information via proximity communication with one or more island chips in the MCM. Additionally, spacers are rigidly mechanically coupled to the top surface of the substrate. In conjunction with the bridge chip, the spacers define cavities on the top surface, which include second electrical connectors. These second electrical connectors are electrically coupled to the TSVs, and communicate additional information with and convey power to the one or more island chips.

    Abstract: Base decks for data storage systems include a spindle motor region, a medium support region, an enclosure sidewall, and a recessed channel. The spindle motor region is configured to support a spindle motor assembly. The medium support region is beneath a storage medium when the storage medium is positioned within the base deck, and the enclosure sidewall surrounds an outer periphery of the storage medium when it is positioned within the base deck. The recessed channel is within the media support region and extends from the spindle motor region to the enclosure sidewall. The recessed channel illustratively has curved sidewalls that converge.
