摘要： Embodiments of the present invention provide a suspension assembly having a dielectric limiter. According to one embodiment, the suspension assembly includes a load beam and a flexure assembly. The flexure assembly includes a metal layer where there are formed a fixing portion fixed to the load beam, main rings, and extending from the fixing portion, sub-rings, and a flexure tongue having moving-side limiter coupling portions defined thereon. Fixing-side limiter coupling portions are defined at the main rings. Dielectric limiters each have a gross length larger than a between-coupling-portions distance between a fixing-side limiter coupling portion and a moving-side limiter coupling portion, and couple the fixing-side limiter coupling portion to the moving-side limiter coupling portion.

摘要： Embodiments of the invention provide, in a compact magnetic disk drive, a stable structure capable of reducing self-oscillation occurring from disk spinning, while suppressing generation of dust and dirt. In one embodiment, a magnetic disk is mounted on a hub of a spindle motor. A clamp is further attached to secure the magnetic disk in position. A plurality of opening portions are formed in the clamp around an axis. A counterweight formed of an elastic material is mounted in the opening portion by being press-fitted therein. The counterweight is less likely to generate dust and dirt through friction during insertion and looseness. A gap is provided between the clamp and the hub at locations near the opening portions. The counterweight has a protruded portion on a side surface of a circular column portion. The protruded portion slides into the gap between the clamp and the hub, counteracting a tendency of the counterweight to drop out of position.

摘要： Embodiments in accordance with the present invention allow a resin member accommodating therein a trace, to have a small thickness. An HDD according to an embodiment of the present invention includes a resin accommodation member fixed to a side surface of arms. Part of a trace is accommodated in a slit formed in the accommodation member. Accommodating part of the trace in the slit helps suppress fluttering of the trace and improve head positioning accuracy. A corrugated surface structure is formed on each of surfaces of the arms and the accommodation member in abutment with each other. The corrugated surface structure is used to position the accommodation member in a pivot direction. The accommodation member, having the corrugated surface structure for positioning on the surface being fixed, can be made to have a thin wall.

摘要： Embodiments of the invention prevent contact between a peripheral edge of a magnetic disk and a counter surface of a ramp when the magnetic disk is displaced. In one embodiment, a ramp is disposed near the peripheral side surface of a magnetic disk. The ramp has magnetic disk retainers each having slide surfaces and counter surfaces respectively facing the recording surfaces of the magnetic disk. Grooves or recesses are formed in the counter surfaces to define relief spaces. When the peripheral side surface of the magnetic disk is displaced toward the counter surface by shocks exerted on the magnetic disk drive, the relief space prevents the peripheral edge from coming into contact with the counter surface. Thus the amount of particles produced by the collision of the magnetic disk with the ramp can be reduced.
摘要翻译：当磁盘移位时，本发明的实施例防止磁盘的周边边缘与斜面的对置表面之间的接触。在一个实施例中，斜面设置在磁盘的周边侧表面附近。斜坡具有各自具有分别面对磁盘的记录表面的滑动表面和相对表面的磁盘保持器。沟槽或凹槽形成在相对表面中以限定浮雕空间。当通过施加在磁盘驱动器上的冲击使磁盘的周边侧面朝向对置面移动时，释放空间防止周缘与对置面接触。因此，可以减少由磁盘与斜坡碰撞产生的颗粒的量。
