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.

Abstract: A temperature control apparatus for a hard disk drive includes: a thermal chamber for receiving a hard disk drive; and an oscillatory air movement generator for generating air movement within a region between the thermal chamber and the hard disk drive when received in the thermal chamber, thereby to facilitate heat transfer between the thermal chamber and the hard disk drive.

Abstract: Apparatus for supporting a disk drive with a rotating disk about a disk axis and an arm which pivots over the disk about an arm axis. The disk axis and the arm axis are perpendicular to the plane of the disk. The apparatus includes a disk drive carrier having a disk drive receiving portion where disk drive can be received, and a housing in which the carrier can be received. A mounting arrangement is provided for supporting the carrier within the housing such that the center of rotation of the carrier is outside the disk drive receiving portion of the carrier. Additionally, a mounting arrangement is provided for supporting the carrier within the housing, comprising a forced pivot at or towards the opposite end of the disk drive carrier, and about which the carrier is fixed for pivotal movement in the housing.

Abstract: A disk drive test apparatus has a plurality of bays each for receiving a respective disk drive to be tested. A plurality of card slots are provided each for receiving a test card via which a disk drive can be tested. Each of the test cards is either an environment test card or an interface test card. The card slots and the test cards are arranged such that each card slot (6) can selectively receive an environment test card or an interface test card. Other arrangements for disk drive test apparatus or disk drive mounting apparatus are disclosed.

Abstract: In an OFDM receiver, a synchronisation pulse for defining a Fast Fourier Transform window is generated by examining the output of a correlator to find a sub-interval within which there is maximum correlation between samples of the symbol separated by the length of the useful part of the symbol. The synchronisation pulse is generated during this sub-interval (102). Adjustments to the timing of the synchronisation pulse are made only if the current error is significant and persistent. A signal representing the amount of adjustment is used to determine phase rotations applied to the output of the FFT circuit.
