Abstract
The headstack of a disk drive is formed with separate sections, each of which supports a plurality of head suspensions. In one embodiment, the sections are blocks on which pairs of head suspensions having UP and DOWN facing sliders are mounted. The blocks are individually positioned and aligned relative to a disk stack. In a second embodiment, head suspensions are supported by a pair of modules. A first module supports suspensions with UP head sliders and a second module supports suspensions with DOWN head sliders. The modules interlock so that an alternating arrangement of UP and DOWN heads result. By use of a comb-like head loading tool, the suspensions that carry the head sliders are spaced and loaded to respective disk surfaces.
