Abstract
A lower cost per unit of storage hard disk drive (HDD) includes multiple disk stacks movably coupled to a guide rail and a head stack assembly (HSA) for accessing the magnetic-recording disks of each of the multiple disk stacks. A disk stack feeding mechanism may be implemented to move each of the disk stacks along the guide rail, and a positioning mechanism may be implemented to align and to temporarily fix a disk stack relative to an HSA. An internal filtering system may also be implemented for keeping contamination-free a compartment in which the disk stacks and HSA are operational.
