    • A precision magnetic head positioner assembly for a Winchester-type hard disk drive storage system includes a main rotatable integral head positioner body and an integral magnetic coil assembly. The positioner body includes outwardly extending integral head positioning arms and a seating surface comprised of two angled lateral seating surfaces. The integral magnetic coil assembly comprises a coil frame and a mounting surface having two angled lateral mounting faces which engage the positioner angled seating surfaces for mounting with fasteners. Precision self-alignment of the positioner seating and bobbin mounting surfaces is provided by an alignment ledge protruding outwardly from the positioner seating surface which engages the lower edge of the bobbin mounting surface. An interference between the positioner seating surface and bobbin mounting surface angles improves mounting alignment and stability.
    • 一种用于温彻斯特型硬盘驱动器存储系统的精密磁头定位器组件,包括主旋转一体式头部定位器本体和整体式电磁线圈组件。 定位器主体包括向外延伸的整体头部定位臂和由两个倾斜的侧面座面组成的座面。 整体式电磁线圈组件包括线圈框架和安装表面,该安装表面具有两个成角度的侧向安装面,该侧面安装面与定位器成角度的座面接合,用于与紧固件一起安装。 定位器座和筒管安装表面的精确自对准由从定位器座表面向外突出的对准凸缘提供,定位器座表面接合筒管安装表面的下边缘。 定位器座表面和筒管安装表面角度之间的干涉改善了安装对准和稳定性。
