摘要： Embodiments of the invention provide a bearing mechanism for a head used in a magnetic disk drive capable of preventing scattering of dust and dirt at a high level and a magnetic disk drive having the same. In one embodiment, a base is provided with a bearing hole. An inner shaft is joined to the bearing hole. The inner shaft is inserted internally in an outer sleeve mounted with a head stack assembly. The outer sleeve is swingably connected to the inner shaft by way of upper and lower bearing mechanisms. A receiving surface is formed around the bearing hole on the base. The receiving surface is higher by a predetermined height than a basic plane of the base. An extended portion is formed on an end portion on a lower side (the end facing the base) of the outer sleeve. A labyrinth seal structure is provided between an end face of the extended portion and the receiving surface.

摘要： Embodiments of the invention suppress the occurrence of turbulence in a disk drive. In one embodiment, an HDD includes a spindle motor for rotating a magnetic disk, and a base for housing the spindle motor therein. The base includes a first bottom surface opposed to the magnetic disk, and a second bottom surface that is opposed to the magnetic disk and that is larger in distance to the magnetic disk than the first surface. A step is formed between the first bottom surface and the second bottom surface, where rotation of the magnetic disk produces an airflow running from the first surface toward the second surface. The step is provided with upright fins extending from the first surface toward the second surface which are stood upright.

摘要： Embodiments suppress a fluttering phenomenon of a wiring structure portion for signal transmission between a head and an FPC. In one embodiment, an actuator has a support portion which accommodates a wiring structure portion. 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 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 suppress fluttering of the wiring structure portion and improve the head positioning accuracy.

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.

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： 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： 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.
