ABSTRACT:
A disk drive includes a base, a spindle motor attached to the base, the spindle motor including a hub having hub apertures, a plurality of disks on the spindle motor and including a first and a second disk, a disk spacer between the first and second disks, and a disk clamp. The disk spacer has a plurality of spacer through apertures. Each of the spacer through apertures extend radially through the disk spacer. The disk clamp has clamp through apertures adjacent to an inner diameter of the disk clamp. Each of the clamp through apertures extend longitudinally through the disk clamp. The clamp through apertures, the hub apertures and the spacer through apertures are aligned for allowing airflow to pass through the apertures when the disks are rotating.
