Abstract
In a disk drive including a conventional head and disk assembly containing a spindle motor for rotating a disk hub at a constant angular velocity and at least one rotating disk mounted to the hub, apparatus comprising a base having a peripheral sidewall surrounding the base. The base supports the head and disk assembly within an interior space defined by the peripheral sidewalls in combination with the base. To reduce the power consumption as well as the operating temperature of the disk drive by controlling and confining the air mass proximate the disk, a shroud is positioned within the interior space and proximate the disk such that the shroud substantially circumscribes the circumference of the disk for an arc of approximately 320 degrees.
