Abstract
An actuator arm design having a close cross section which greatly improves the performance of the disc drive. The actuator arm is formed of a top skin, a bottom skin, and a core. The core may be formed of a corrugated metal, or a foam metal, or a combination of the two. As a result of this structure of the arm, the arm is highly stiff, yet low mass which yields an arm having a high resonant frequency.
