摘要： Embodiments of the invention provide a disk drive capable of reducing vibrations of a disk generated by an airflow produced as the disk rotates. In one embodiment, a disk drive comprises: a rotary magnetic disk, a base for housing the magnetic disk, a top cover for closing the disk in the base to form an enclosure, a circulating filter arranged externally of the magnetic disk to trap dust within the enclosure, and an airflow guide for guiding an airflow which flows out of the circulating filter more to the center side than to the outer edge portion of the magnetic disk. Further, a shut out portion is provided in the vicinity of the outer edge portion of the magnetic disk to shut out an airflow which flows out in the vicinity of the outer edge portion.

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： Providing a zoom lens system that can excellently correct aberrations over entire range from a wide-angle end state W to a telephoto end state T in spite of having a high zoom ratio including, in order from an object, a first group G1 having positive power, a second group G2 having negative power, a third group G3 having positive power, a fourth group G4 having negative power, and a fifth group G5 having positive power. When zooming from the wide-angle end state W to the telephoto end state T, a distance between the first group G1 and the second group G2 increases, a distance between the second group G2 and the third group G3 decreases, a distance between the third group G3 and the fourth group G4 increases, and a distance between the fourth group G4 and the fifth group G5 decreases. Given conditions are satisfied.

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： In a tip portion structure basically having a substrate, a plate spring, and a ground block, the substrate is attached to a signal line on a back surface of the substrate and is contacted on the tip with the signal electrode of the DUT placed on a device stage. The plate spring is made of a resilient material, placed on the front side of the substrate, and positioned to apply a pressure to the substrate. The ground block is positioned between the signal line and the device stage functioned as a ground electrode of the DUT. Alternatively, the tip portion structure further may have a ground plate or a ground surface formed of a conductive thin plate covering entirely the front surface of the substrate, and shaped to surround the signal line in cooperation with the ground block. A plurality of the signal lines may be arranged in parallel on the same plane of the substrate. Another tip portion structure is based on a coaxial cable to be cut from the center at a plane perpendicular to the axial direction thereof along one or more oblique plane. A metal ring fitted over a periphery of the coaxial outer conductor may be used.
