摘要： A spindle motor includes a spindle motor hub that supports one or more disks, and has a contact area reduction portion that minimizes the area of contact between the hub and a disk when the disk is mounted to the hub. The spindle motor hub includes a hub body having a cylindrical sidewall that includes a contact section around which the disk extends and a non-contact section. The non-contact section is constituted by the contact area reduction portion. An outer diameter of the cylindrical hub body at the contact section is greater than an outer diameter of the cylindrical hub body at the contact area reduction portion of the non-contact section.
摘要翻译：主轴电动机包括支撑一个或多个盘的主轴电机集线器，并且具有接触区域减小部分，当盘安装到轮毂时，该接合区域减小部分使得毂和盘之间的接触面积最小化。主轴电动机毂包括具有圆柱形侧壁的轮毂体，该圆柱形侧壁包括盘延伸的接触部分和非接触部分。非接触部由接触面积缩小部构成。在接触部分处的圆柱形轮毂体的外径大于非接触部分的接触面积减小部分处的圆柱形轮毂体的外径。

摘要： An HDD includes a head stack assembly, a voice coil motor, and a retracting pin unit. The retracting pin unit includes a mobile retracting pin generating a retracting force to maintain the actuator arm at a predetermined position by interacting with the magnet when the read/write head is parked, and coupled to the bobbin to be capable of relatively moving with respect to the bobbin toward the magnet when the bobbin is separated from the magnet due to an external shock. A head on disk phenomenon, in which the parking state of the read/write head is removed when an external shock such as a linear shock or a rotary shock, which may be generated as the HDD is installed in a notebook computer, is applied to the HDD, may be reduced.
摘要翻译： HDD包括磁头堆叠组件，音圈电动机和缩回销单元。回缩销单元包括移动缩回销，其产生回缩力，以通过在读/写头停放时与磁体相互作用而将致动器臂保持在预定位置，并且耦合到线轴以能够相对于当筒管由于外部冲击而与磁体分离时，线轴朝向磁体。当在笔记本计算机中安装HDD时可能产生的诸如线性冲击或旋转冲击的外部冲击时，读取/写入头的驻留状态被移除到磁盘上的磁头现象 HDD可能会减少。
