Abstract
A disk drive system includes a mechanism for positioning a movable transducer member in the absence of electrical power to the drive system. The mechanism includes a ferromagnetic lever arm pivotably positioned to engage a movable transducer member and, by such engagement, to move the transducer to a predetermined location. An electromagnet attracts the lever arm to a position clear of the movable transducer member in the presence of electrical power to the drive system, and a spring moves the lever arm into engagement with the movable transducer member when the electromagnet is not energized.
