摘要： A disk drive structure maximises the axial length available for mounting disks within a predetermined height such as dictated by a form factor. A cast aluminium box frame 12 is used which supports the spindle and actuator assemblies and forms a part of the head disk enclosure in cooperation with a drawn metal cover 10. The box frame captures the spindle 9 and actuator shafts 40 at each end to ensure maximum overall assembly stiffness and to minimise the axial length required by the structure supporting the spindle. The box casting geometry is angled to establish the casting/cover joint around the disks before the diameter of the disks parallel to the width form factor, so that only the thinner cover is interposed in the region where the disks most closely approach the form factor. The cover and box frame are sealed and secured to one another by a thin compliant tape 11 that does not contribute stress to the box frame during thermal cycling.

摘要： A disk drive within the dimensional confines of a form factor can optimise volumetric density by using the full height dimension to house disks (13), but must thereafter utilise the remaining space for electrical components. The structure shown uses a stack of parallel cards with an interface card (84) on the rear end wall to provide the principal drive control and data circuits outside the head-disk assembly (HDA; 13). The motor driver circuitry (107, 111) is mounted on a flat flexible cable (72) and is secured to the front wall (18) at the opposite end of the drive in heat transfer relation. The heat generating motor drive circuits are physically isolated from the data/control circuits by the frame and HDA while some of the printed circuit cards are secured to the frame in a manner that enhances rigidity; the allocation of modules to the cards anticipates flow of data and control signals so as to minimise the number of connections and signal delays that impair performance.

摘要： A disk pack assembly for use in a disk drive has disks which are alternately diametrically offset about a spindle axis of rotation. The disks are positioned as a function of the their outer edges such that alternate opposite outer edges line up as though they were the outer edges of centered nominal diameter disks. This results in an increase in the number of axial nodal points for potential imbalance moments and reduces the amplitude of associated vibrations. Disk spacers are also alternately diametrically offset about the spindle axis so that pairs of like components tend to balance each other to minimize potential vibrations.

摘要： A disk drive includes a fastening structure to secure a shaft between parallel walls which will secure and locate the shaft without inducing a distortion of the walls. One end of the shaft is secured to the adjacent wall and the other end of the shaft is secured through a wall opening using an annular slug 43 and a deformable washer 45 which is compressed by a bolt 41 attached axially to the shaft end to cause the deformed washer to engage the surfaces defining the wall opening 32. The uniform axisymmetric expansion of the washer does not affect the position of the shaft and the radial force secures the shaft end without influencing the structure of the casting.
