There is provided a disk drive including a disk drive base and a spindle
motor hub. The disk drive further includes first and second disks
disposed about the spindle motor hub. The disk drive further includes a
disk plate coupled to the disk drive base. The disk plate includes a
plate body extending between the first and second disks for modifying air
flow adjacent the first and second disks. The plate body includes a plate
body thickness in a direction parallel to an axis of rotation of the
spindle motor hub. The disk plate further includes an inner edge
extending from the plate body and disposed towards the hub. The inner
edge includes an edge thickness in a direction parallel to the axis of
rotation less than the plate body thickness for mitigating against
contact between the inner edge and the first and second disks.
