ABSTRACT:
In a disk drive, a stationary air guide for channeling windage flowing proximate a surface of a single rotating disk toward an air vane of an air vane actuator latch. The air guide has two members, a first member is positioned partially over an upper surface of the disk and a second member is positioned partially over a lower surface of the disk. The air guide members are proximate the respective surfaces in a spaced apart parallel relation thereto. Each air guide member further contains a shrouding member that maintains the air flow near the disk surface and a channeling member that channels the air flow toward the air vane. As such, windage from the rotating disk is channeled to a distal end of the air vane such that sufficient torque is produced by the windage from the single rotating disk to unlatch the latch mechanism.
