Abstract
An aerodynamically powered release latch mechanism for a fixed disk data file is disclosed. An airflow generator disk is commonly journalled with a single data storage disk for generating airflow in an enclosed chamber. A latch is journalled for rotation relative to a base casting and has an axis of rotation spaced a predetermined distance away from the periphery of the data storage disk. The latch includes a vane movably disposed in a space defined between the airflow generator disk and the data storage disk so as to be deflected by airflow generated by rotation thereof. A releasable engagement mechanism engages a rotary actuator assembly in a locking position in the range of relative movements therebetween whenever airflow is insufficient to deflect the vane. A bias spring is operable between the latch and the base casting for maintaining the engagement mechanism in locking position in the absence of airflow.
