Abstract
A hard disk drive for providing memory storage for a computer includes a rotatable stack of disks and a plurality of rotary actuator arms mounting magnetic heads for movement radially of the disks to read/write magnetically encoded data on each surface thereof. The actuator arms which extend between adjacent spaced disks are pivotally mounted in a scissor-like arrangement so that the radial tracking movement of the heads thereon occurs in angularly spaced locations in the disk stack. The rotary actuators are driven by a pair of drive arms extending in opposed relationship from the actuator pivot axis.
