Abstract
A lower cost per unit of storage hard disk drive (HDD) includes multiple disk stacks and a head stack assembly (HSA) movably coupled to a rail for accessing magnetic-recording disks of each of the multiple disk stacks. Such an HDD may include multiple columns of linearly-arranged disk stacks with an HSA corresponding to each column, where the disk stacks on each side of the rail are positioned for asynchronous access by the HSA, and may include multiple HSAs coupled to the rail, where the disk stacks on each side of the rail are positioned for simultaneous access by respective HSAs being moved either synchronously or independently.
