摘要
A system and method for stabilizing air flow in a shroud to disk region in a hard disk drive are disclosed. One embodiment provides a hard disk drive having a shroud with machined aerodynamic annulus insertions thereon for stabilizing the Ekman layer of air flow at the peripheral ends of the hard disks and the shroud. The aerodynamic annulus insertions are positioned in between disk pairs at approximately 1 mm from the peripheral ends of each disk to stabilize the air flow as the disk rotate and to ensure that the air flow leaves the hard disk drive at a fixed location.
