  • Patent number: 8524052
    Abstract: Apparatus and method for cooling a recording media disk in a deposition system. A manifold spacer including an input port to receive a coolant gas and a first output port to output the coolant gas couples a pair of cooling plates together, the pair of cooling plates having opposing surfaces spaced apart by the manifold spacer to accommodate a passage of disks to be cooled. A first shower manifold is coupled to a first of the pair of cooling plates, the first shower manifold receives the coolant gas from the first output port in the manifold spacer and outputs the coolant gas flow in a first direction perpendicular to the opposing cooling plate surfaces and toward the media disk to be cooled.
