Abstract: The base of a disk drive defines an interior shroud surface. The interior shroud surface is configured to follow a portion of the curvature of the disk at a distance from the outer diameter of the disk. The interior shroud surface of the base may define one or more channels for modifying the airflow developed as the disk rotates. The interior shroud surface defines an opening to enable the head stack assembly to pivot over the disk, which opening is bounded by a leading shroud portion and a trailing shroud portion. The leading shroud portion and/or the trailing shroud portion may also define a channel or channels for modifying the airflow that is developed as the disk rotates.

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.

Abstract: A disk drive including a disk drive base. The disk drive further includes at least one rotatable disk which includes a disk surface extending to an outer disk edge. The disk drive further includes a head stack assembly rotatably attached to the disk drive base in operable communication with the disk. The disk drive further includes an airflow suppressor comb coupled to the disk drive base and stationary relative to the disk drive base during operation of the disk drive. The comb includes a comb body disposed adjacent to the outer disk edge, and at least one tine extending from the comb body along the disk surface for mitigating disk rotation induced airflow upon the head stack assembly adjacent to the disk surface.
