摘要： Terminals of a flexible printed circuit board and terminals of a wiring trace in a head suspension assembly are to be connected with each other by soldering without causing a soldering defect. In an embodiment, a terminal structure of a multi-connector in a wiring trace which includes an insulating layer and a conductor pattern portion formed on a surface of the insulating layer is provided with exposed portions of terminals exposed from apertures formed in part of the insulating layer and is also provided with lining portions adjacent to the exposed portions in a longitudinal direction of the conductor pattern portion and bonded to the insulating layer. Even if terminals of the multi-connector are cracked when soldered, not only conductivity is ensured, but also it is possible to strengthen the terminals, because the lining portions of the terminals are bonded to the insulating layer.

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.
摘要翻译：本发明的实施例涉及根据跌倒状态将盘驱动装置的磁头回缩到缩回位置，并且抑制由于错误的下降判定引起的性能下降以及头盘崩溃的损坏的发生。根据本发明的一个实施例，在硬盘驱动器（HDD）中，伺服控制器在预定定时将磁头滑块移动到斜坡侧的气缸，以便下降确定器确定其正在下降并且卸载控制器启动卸载过程。这缩短了下降确定器确定其下降到头部滑块缩回到缩回位置之间的时间。此外，通过放松用于安全的跌倒判定条件，防止了错误判定的增加。而且，如果没有确定它正在下降，它会缩短磁头滑块在搜索之前返回到初始位置的时间。

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.
