Abstract: A disk file comprises a head disk enclosure 1 connected to a support frame by a plurality of isolation mounts. Each isolation mount comprises a constrained layer flexure 23 which is rigidly attached at both ends to a bracket 25 of the support frame. Located in an aperture in the constrained layer flexure is a resilient grommet 24. This grommet supports a bolt 27 which passes through the grommet and into the head-disk enclosure casting.

Abstract: A linear actuator for positioning the heads of a disk file relative to tracks on the disks employs a ceramic material having wear properties superior to steel in guide surfaces for guiding a head supporting carriage running on rotary bearings in contact with the guide surfaces. The preferred ceramic material is tetragonally stabilized zirconia.

Abstract: To facilitate maintenance, a disk drive assembly 40 includes a disk-head assembly (HDA) 45 and an electronic card pack 47 both releasably mounted on a carrier frame 49 e.g. using quick-release shock mounts 44, 46. In use, a carrier assembly connector plug 59 mounted at the rear edge of a circuit hoard included within the electronic card pack engages a stationary connector plug 81 mounted within a host system receiving unit. The carrier frame has guide rails 42 which are received by guide grooves or tracks 87 within the receiving unit to allow the carrier assembly to be inserted in and extracted from the receiving unit. Alignment pins 77 protruding from the connector plug 81 engage and align the connector plug 59 as the carrier assembly is inserted into the receiving unit. A locking handle 53 may provide a force to maintain the carrier assembly in place during operation.
