Abstract
A shroud feature and method for incorporating an airflow shroud feature in a disc drive assembly. The airflow shroud feature is connected to the cover of the disc drive rather than the base plate. When the disc drive cover incorporating the shroud feature is placed on the disc drive, the shroud feature surrounds at least a portion of the circumference of the outer peripheral surface of the disc to reduce turbulence when the disc is operated. The shroud is rigidly connected to the top cover by engagement of the shroud with a physical feature of the top cover. The shroud operably directs air-flow along the peripheral edge of the disc during drive operation when the cover is installed on the base plate.
