Abstract
A disk drive includes a spindle motor assembly mounted on an enclosure and at least two disks. The disks are mounted on a hub of the spindle motor assembly. Each of the disks have a magnetic medium deposited between an inner circumference and an outer circumference. The disks define a volume therebetween wherein airflow is generated when the disks rotate. The disk drive also includes an airflow spoiler positioned between the disks. The airflow spoiler has a spoiler mounting portion and a non-data bearing extending portion. The spoiler mounting portion is configured to be mounted on the hub of the spindle motor assembly. The non-data bearing extending portion is connected to the spoiler mounting portion and extends outwardly therefrom into the volume defined between the disks. The non-data bearing extending portion extends at least partially over the magnetic medium.
