Disk drive including a disk plate with a reduced thickness inner edge disposed towards a spindle motor hub

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.
