A hard disk drive having an actuator assembly in which only flexible integral load beams are used in the armstack structure. The load beams are assembled in a stack on a tubular actuator member along with the movable coil member of the actuator motor, or other actuator drive mechanism, and after alignment are secured to the tubular member to from a separate actuator assembly. This actuator assembly is applicable to both rotary and linear actuators in disk drives. In the rotary actuator assembly structure, the tubular member or hub is secured to a bearing housing journaled in the base of the drive for rotation about the axis of the tubular member. In the linear actuator structure, the tubular member, is fastened to the moving part of the linear drive mechanism and linearly moves with that mechanism.
