Abstract
A head loading mechanism for a disk drive. When power to the disk drive is disconnected, an actuating spring is released. Movement of the spring causes a plunger to contact a bracket on the actuator arm, moving the actuator arm over a parking zone. Further movement of the spring causes blades to lift read/write heads mounted on the actuator arm away from disk surfaces. When power is restored, a motor compresses the spring and returns the plunger and the blades to their original positions.
