摘要： A disk file comprises a disk stack subassembly and a head positioning actuator each mounted on opposite sides of a central box frame. The disk stack subassembly has a non-rotating central spindle and an in-hub electric motor whose stator is mounted on the spindle. The rotor of the motor is mounted internally of a hub supported for rotation about the spindle by two bearings at opposite ends of the spindle. A stack of disks is mounted externally on the hub. The box frame is open to one side and the opposite ends of the stationary spindle are located and fixed in the frame so that the disk stack subassembly spans the open side. Because of the symmetry and rigidity of the design, susceptibility to thermal or vibration induced misregistration is reduced. Finally a cover completes the enclosure.

摘要翻译： 磁盘文件包括磁盘堆叠子组件和头部定位致动器，每个安装在中心盒框架的相对侧上。 磁盘堆叠组件具有非旋转中心心轴和定心安装在心轴上的内轮毂电动机。 电动机的转子安装在一个轮毂的内部，该轮毂可以通过主轴相对两端的两个轴承支承，以绕主轴转动。 一堆磁盘从外部安装在集线器上。 盒框架一侧开放，固定主轴的相对端定位并固定在框架中，使得盘片组件跨越开放侧。 由于设计的对称性和刚性，减少了对热或振动引起的对准的敏感性。 最后一个封面完成了外壳。
