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.

摘要： Embodiments in accordance with the present invention improve the head characteristic and avoid collisions between a head element section and a recording disk. A hard disk drive according to an embodiment of the present invention performs TFC (Thermal Fly height Control) to adjust the clearance between the head element section and recording disk by means of thermal expansion. A head slider includes a TFC heater. The hard disk drive detects its acceleration and controls the TFC heater in accordance with the detected acceleration, thereby reducing the probability of collision between the head element section and recording disk. Further, the hard disk drive detects residual vibration prevailing after impact application. The heater turns back ON when the residual vibration becomes lower than a reference level.

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.
