发明名称 LAMINATED ACTUATOR ARM AND HARD DISK DRIVE HAVING THE SAME
摘要 A laminated actuator arm and a hard disc drive with the same are provided to maintain the stiffness in view of the structure of an actuator arm due to the first material layer including a steel material and to enhance an attenuation characteristic of shock and vibration load due to the second material layer including a damping material. An actuator arm of a hard disc drive includes the first material layer(60) and the second material layer(62) laminated on the first material layer(60). The first material layer(60) includes metal, and the second material layer(62) includes a damping material. Aluminum is used for the first material layer(60) instead of metal. Polyimide or epoxy is used for the second material layer(62) instead of the damping material. A plastic insert is attached to the first material layer(60) and the second material layer(62) in order to support a voice coil.
