Abstract:
A disk drive comprising:a drive housing; an actuator hub that is movably coupled to the drive housing; one or more transducer assemblies coupled to the actuator hub; a first actuator arm that extends away from the actuator hub, the first actuator arm supporting less than two transducer assemblies, the first actuator arm including a first uncoupled side, the first actuator arm having a weighted segment that is homogeneously formed into the first uncoupled side, the weighted segment of the first actuator arm being formed by a material removal operation; and a spaced apart second actuator arm that extends away from the actuator hub, the second actuator arm supporting at least one transducer assembly; wherein the first actuator arm has a weight that is greater than the weight of the second actuator arm, and wherein the first actuator arm and the second actuator arm have different resonance characteristics.
