摘要： A rotational member and a stationary member included in a spindle motor provided with air bearings are electrically connected while the bearing is rotating, and abrasion of the rotational member and the stationary member at stages of starting and stopping and damaging the rotational member and the stationary member by external shocks that may be exerted thereon during transportation and handling are avoided. In one embodiment, a sleeve is formed integrally with a motor base. The sleeve has an inside surface serving as a radial-bearing surface that forms a radial bearing together with the outside surface of a rotational shaft, and a thrust-bearing surface that forms thrust bearing together with a thrust plate attached to the rotational shaft. The radial-bearing surface of the sleeve is provided with a recess (groove) for holding lubricating oil while the rotational shaft is rotating. A gap not forming a bearing is formed between the circumference of the thrust plate and the inside surface of the sleeve to hold the lubricating oil while the rotational shaft is rotating.

摘要： The structure is made such that an aerodynamic latch is provided in an outer portion of a magnetic disc, a front end portion exposed to a wind in the aerodynamic latch is formed to be shorter than an outer peripheral surface of the magnetic disc, and the wind receiving portion of the aerodynamic latch moves an air stream outlet from an end surface of the magnetic disc and a shroud in a direction of forming a flow passage for passing through a portion apart from the magnetic disc. Accordingly, a stable aerodynamic latch drive can be achieved and an air stream within the disc is not disturbed, so that it is possible to reduce a flutter and a consumed electric power.
摘要翻译：该结构使得在磁盘的外部设置空气动力学闩锁，在空气动力学闩锁中暴露于风中的前端部分形成为比磁盘的外周表面短，并且风空气动力学闩锁的接收部分使空气流出口从磁盘的端面移动，并且护罩沿形成流路的方向移动以通过与磁盘分离的部分。因此，可以实现稳定的空气动力学闩锁驱动，并且盘内的空气流不被干扰，使得可以减少颤动和消耗的电力。
