In a disc drive with an integrated casting comprising the housing for the stepper and spindle motors, the transducer is mounted on a normal bearing pivot assembly 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. The actuator arm is formed of a self-lubricating polymer or other lightweight self-lubricating material. This way, wear on the gear is reduced; and as the teeth are worn, the gear is still tightly biased against the pinion to maintain accurate movement of the actuator arm with rotation of the pinion.
