摘要： An actuator arm with suppressed arm fluttering is provided. On a main surface of each actuator arm in an actuator arm unit there are formed a rigid area which extends centrally in the longitudinal direction and flow uniformizing areas which are each formed in a substantially flat shape extending longitudinally in adjacency to the rigid area and which are thinner than the rigid area. A balance aperture is not formed in the portion where the flow uniformizing areas and the rigid area are formed, to diminish arm fluttering. Instead of a balance aperture, the flow uniformizing areas also exhibit the effect of reducing the weight of the actuator arm.

摘要： Embodiments of the invention are directed to suppressing a fluttering phenomenon of a wiring structure portion which is for signal transmission between a head and an FPC. In one embodiment, an actuator has a support portion which accommodates a wiring structure portion for signal transmission between a head and an FPC. The wiring structure portion is provided at a rear end portion thereof with a wide tab, the tab having pads for connection with the FPC. The support portion has a convex wall portion which is formed so as to overlap a front end portion of the tab. An air current occurs at an end portion of a magnetic disk in the vertical direction. When the head accesses a track present on the inner periphery side of the magnetic disk, the tab approaches the disk end portion. Since the convex wall portion protects the tab against the air current, it is possible to prevent oscillation of the tab. Consequently, it is possible to suppress fluttering of the wiring structure portion and improve the head positioning accuracy.
摘要翻译：本发明的实施例旨在抑制用于头部和FPC之间的信号传输的布线结构部分的颤动现象。在一个实施例中，致动器具有支撑部分，其容纳用于头部和FPC之间的信号传输的布线结构部分。布线结构部分在其后端部设置有宽突片，突片具有用于与FPC连接的垫。支撑部具有形成为与突片的前端部重叠的凸壁部。在磁盘的垂直方向的端部发生气流。当头部进入存在于磁盘的内周侧的轨道时，突片接近盘端部。由于凸壁部分防止突片抵抗气流，因此可以防止突片的振动。因此，可以抑制布线结构部分的颤动并提高头部定位精度。

摘要： Turbulence of an airflow returning to a magnetic disk along the base sidewall of a HDD is reduced to thereby reduce flutter of an actuator or a magnetic disk caused by the airflow, thus improving read/write performance. An HDD according to an embodiment of the present invention comprises a base, a top cover fixed to the base, a motor for rotating a magnetic disk, an actuator for moving a head which gets access to the magnetic disk, a ramp slope portion on which an extreme end is ridden up, a ramp support portion for supporting the ramp slope portion, and a stage for holding the ramp support portion. A flow passage is formed which runs toward the magnetic disk through an area near the ramp support portion on the side of the top cover. An inclined portion running toward the bottom of the base is formed on the end of the flow passage on the side of the magnetic disk.

摘要： A rebounding phenomenon of an actuator assembly is to be prevented and device assembling work and maintenance work are to be carried out separately from stopper removing work. In one embodiment, a magnetic disk device includes a stopper 50 for restricting a turning range of an actuator assembly 8 having a coil support 22 in a magnetic disk device. In the stopper 50, rubber 51 is cantilevered by a support rod 261 so as to undergo a moment of force and fulfill a shock absorbing function in order to restrict an excessive movement of the actuator assembly 8 to an inner or an outer side when the rubber 51 is abutted against a first arm 22a or a second arm 22b of a bifurcated shape of the coil support 22, the support rod 261 is disposed outside a turning track of turning ends of the first and second arms 22a, 22b of the coil support 22, and a permanent magnet 52 is embedded in the rubber 51 to attract the first and second arms 22a, 22b.

摘要： A disk clamp has a data position in a recording track that is resistant to positional deviations even after temperature cycling is conducted. The distribution of data positions can be centered in the vicinity of the center position. A disk top clamp and hub are made from materials that are stable in terms of chemical properties over a temperature range in which the disk recording apparatus is used and have such a coefficient of elasticity that a clamping force required to clamp the recording disks while the disk recording apparatus is in use can be obtained from the tightening force to tighten the screws. The material of the top clamp and the hub has a thermal expansion coefficient that is close to that of the recording disk.
