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: Disk drives including suspensions and head gimbal assemblies in which the load beam pitch angle is reduced exhibit a reduced disk flutter induced track mis-registration (TMR) at the disk outer diameter. The reduction in the load beam pitch angle may be achieved through variations in the load beam, hinge and/or mount plate configurations, relative positions and/or thickness.
