Abstract
In a disc drive, the normal bearing pivot assembly is replaced with a combination of a lightweight actuator arm and biasing strip spring. One end of the strip spring is mounted to a block and the effective force of the spring is aligned with the actuator arm running toward the stepper motor. The other, or head end of the actuator arm contains a gear sector having gear teeth on its face which mesh with a pinion on a motor shaft so rotation of the motor shaft across the face of the gear sector causes movement of the head mounting arm.
