  • Publication number: 20090122443
    Abstract: A disk drive carrier assembly for carrying plural disk drives is provided. The assembly has a casing having first and second opposed ends, opposed sides, a top and a bottom. Drive cards are provided in the casing. Each drive card has a disk drive receiving portion for receiving a disk drive and provides at least one of a power and a data connection to a disk drive. A baffle arrangement splits an air stream entering the casing at a first end of the casing to flow over the disk drive receiving portion of each of the drive cards. The drive cards and the baffle arrangement are arranged so that air flows only in parallel over the disk drive receiving portion of each of the drive cards. In this way, each disk drive receiving portion receives air that has not passed over another disk drive receiving portion of the assembly.

  • Publication number: 20080239564
    Abstract: An apparatus for controlling the temperature of a disk drive during manufacture of the disk drive has a cell having a mounting arrangement to which a disk drive can be mounted and having walls defining a volume in which the disk drive is received when mounted to the mounting arrangement during manufacture of the disk drive. At least one wall of the cell adjacent said volume is heat conductive and is arranged such that a disk drive when received in the volume does not touch said at least one wall. An air-agitating device agitates air between the at least one wall and a disk drive when received in the volume to encourage heat transfer between said at least one wall and a disk drive when inserted into the volume. The air-agitating device is mounted so as to be vibrationally isolated from a said disk drive when mounted in the cell.

  • Patent number: 6008984
    Abstract: A mounting for a disk file comprises a carrier defining a space into which the disk file can be removably inserted for operational use. The carrier has a base and two opposed sides and, and first and second wedges and which are movable to act between the main body of the disk file and the side of the carrier, to secure the disk file against movement relative to the carrier. The wedges include wedges which are movable in a vertical direction by a control linkage operated automatically when the disk file is inserted into the carrier structure.
