    • A clamping structure for disk drive for receiving a disk includes a spindle hub, a spacer, and a clamp ring. The spindle hub has a flange at a first end thereof. The flange has a first protruding portion. The discs are stacked on the first protruding portion. The first spacer is interposed between adjacent ones of the disks. The clamp ring is fixed to a second end of the spindle hub. The clamp ring has a second protruding portion for biasing the disks toward the flange of the spindle hub. In a process of forming a holder arm of the disk drive, the tip of a holder arm is contoured by wire cutting method after the holder armed is roughly formed from a metal body. In the wire cutting method, a voltage is placed between the metal body and the wire. The tip of the holder is contoured by the wire by bringing the wire into contact with the metal body.
    • 用于接收盘的盘驱动器的夹持结构包括主轴毂,间隔件和夹紧环。 主轴毂在其第一端具有凸缘。 凸缘具有第一突出部分。 盘被堆叠在第一突出部分上。 第一间隔件置于相邻盘之间。 夹紧环固定在主轴毂的第二端。 夹紧环具有第二突出部分,用于将盘朝向主轴毂的凸缘偏置。 在形成磁盘驱动器的保持臂的过程中,在从金属体大致形成保持器之后,保持臂的末端通过线切割方法成形。 在线切割方法中,在金属体和线之间放置电压。 通过使导线与金属体接触,保持器的尖端由导线成形。
