    摘要: Embodiments of the present invention relate to retracting a magnetic head of a disk drive device to a retract position in accordance with a fall state, and to suppressing the performance degradation due to erroneous fall determinations as well as occurrence of damage by a head-disk crash. According to one embodiment of the present invention, in a Hard Disk Drive (HDD), a servo controller moves a head slider to a cylinder at the side of a ramp at a predetermined timing that a fall determiner determines that it is falling and an unload controller starts an unload process. This shortens the time between determination by the fall determiner that it is falling to retraction of the head slider to the retract position. Furthermore, it prevents increase of the erroneous determinations by relaxing the fall determination condition for safety. Also, it shortens the time that the head slider returns to the initial position before the seek in case that it is not determined that it is falling.

    摘要: Embodiments in accordance with the present invention relate to suppressing deterioration in rigidity and dynamic characteristics of a tab even when an initial point of contact between a tab and a ramp during unloading is set closer to the outer periphery of a disk. A data storage device in one embodiment of the present invention includes a head, a ramp for unloading the head, a load beam having a head support portion for supporting the head and a tab adapted to slide on a sliding surface of the ramp on a front end side with respect to the head support portion, and an actuator having the load beam and adapted to actuate the head for loading and unloading. During unloading, a portion of the tab offset from the center in the transverse direction of the tab first comes into contact with the sliding surface of the ramp. The load beam has a flange formed to be bent and continuously from the front end portion of the tab up to both ends of the head support portion.

    摘要: A rotating disk storage device is provided with a charging filter capable of efficiently removing dust staying in the interior of the device. In one embodiment, a charging filter is disposed below a magnetic disk and on a bottom of a base. The charging filter has plural through holes by forming a fibrous electret filter medium in a pleat shape. The through holes are formed so as to face a flowing direction of air. Dust, which is moving together with the air flow, is polarized and is attracted to the charging filter. The charging filter can collect even very fine particles without causing such problems as clogging and pressure loss. The pleat portion, which forms the through holes, further exhibits an air flow uniforming effect.
