ABSTRACT:
A disk drive or direct access storage device (DASD) of the type having multiple disks and multiple actuator arms, both the disks and the actuator arms assembled in a stacked manner, advantageously assembled with the locating surface or flange of the actuator disposed on the opposite side of the stacked actuator arms from the side of the disk stack having the locating surface or flange for the disk hub. This opposite flange design results in a substantial reduction in the effects of tolerance buildup and therefore permits the design of the disk drive equal in all other respects to a conventional same side flange arrangement, but permitting additional disks, lower height, less tightly defined tolerances on components or the use of cheaper manufacturing techniques and technologies for recording data.
