Abstract
An apparatus and associated method are described which reduce air turbulence in a disc drive assembly. In a method of use, a groove is machined into a side portion of an actuator arm and then a streamlined actuator arm side rail is inserted into the groove to provide streamlining characteristics to the actuator arms. An actuator arm is provided which has a groove which extends along a side portion of the actuator arm. A streamlined side rail is attached to the side portion of the actuator arm, and is preferably arrowhead-shaped so that the side rail mates with the groove. The streamlined side rail reduces air turbulence in the disc drive caused by air flow against and around the actuator arms, yielding an improvement in the power consumption of the disc pack spindle motor.
