摘要： A disc stack assembly for use in a disc drive. A spindle motor hub includes an annular ring recess. A disc is clamped to the spindle motor hub by a disc clamp assembly comprising a clamp plate and a retaining ring. The clamp plate includes an inner ring engagement portion, an outer disc engagement portion, and an initial, substantially planar shape in an undeformed state. The retaining ring is secured within the annular ring recess and maintains the clamp plate in a conically deformed state so that the inner ring engagement portion of the clamp plate applies a first moment force against the retaining ring while the outer disc engagement portion of the clamp plate applies a second moment force as an axially directed clamping force upon the disc.

摘要： A method for forming a disc stack assembly suitable for use in a disc drive. A number of discs are loaded onto a spindle motor hub and a disc clamp assembly is installed to secure the discs to the hub. The disc clamp assembly includes an annular retaining ring and a substantially planar, disc shaped clamp plate. The annular retaining ring is secured within an annular ring recess of the spindle motor hub and deforms the clamp plate so that the clamp plate applies an axially directed clamping force to the discs. The disc clamp includes an annular hat flange. The disc stack assembly is preferably balanced by selectively removing material from the hat flange or by attaching a balance weight to the hat flange.

摘要翻译： 一种用于形成适于在盘驱动器中使用的盘堆叠组件的方法。 将多个盘装载到主轴电机毂上，并且安装盘夹组件以将盘固定到轮毂。 盘夹具组件包括环形保持环和基本上平面的盘形夹板。 环形保持环固定在主轴电动机毂的环形环凹部内并使夹板变形，使得夹板向盘施加轴向定向的夹紧力。 圆盘夹具包括一个环形帽法兰。 优选地通过从帽子法兰上选择性地去除材料或者通过将平衡重物附接到帽子凸缘来平衡盘堆叠组件。

摘要： Embodiments of apparatus are directed to a rotational shock tester system comprising a disc drive support system, a drop mechanism and an impact apparatus. The disc drive support system includes a rotation plate, wherein a disc drive is coupled to the rotation plate. The drop mechanism is coupled to the disc drive support system and includes an elevating apparatus, wherein the elevating apparatus elevates and releases the rotation plate which is supporting the disc drive. The impact apparatus is releasably coupled to the drop mechanism and is aligned with the rotation plate such that upon release of the rotation plate, the rotation plate impacts the impact apparatus such that the impact apparatus imparts an angular acceleration to the rotation plate and imparts a rotational shock to the disc drive.
