摘要： Embodiments of the present invention securely latch an actuator rotated by an external impact. In an embodiment of the present invention, a latch and an actuator have a structure in which the latch can latch the actuator at two different swing angles. The swing angle of the latch is an angle in rotation centered on a rotational shaft (rotation angle). The latch may be engaged with the actuator at a shallow angle, or the latch may be engaged with the actuator at a deeper angle. Since the latch is able to latch the actuator at different swing angles, the actuator can be securely latched.
摘要翻译：本发明的实施例牢固地闩锁由外部冲击旋转的致动器。在本发明的实施例中，闩锁和致动器具有这样的结构，其中闩锁可以以两个不同的摆动角度来锁定致动器。闩锁的摆动角度是以旋转轴为中心的旋转角度（旋转角度）。闩锁可以以较小的角度与致动器接合，或者闩锁可以以更深的角度与致动器接合。由于闩锁能够以不同的摆动角度锁定致动器，所以致动器可以被牢固地锁定。

摘要： Embodiments of the present invention effectively control, by a simple structure, floating of a rotor of a fluid dynamic bearing motor mounted in a hard disk drive. In one embodiment, a base is formed of a magnetic material. The attractive force caused by the magnetic force acts between a bottom of the base and a magnet unit that is constituted of a rotor magnet and a back yoke. This makes it possible to attract a rotor to the base against the buoyant force produced by a thrust bearing, and thereby to effectively control the rotation of the rotor. On the bottom of the base, at a position facing the magnet unit, a convex part protruding from the inner surface of the base is formed in a ring-shape. Adjusting the height, or the width, of the convex part makes it possible to control the magnetic back pressure applied to the rotor.

摘要： A magnetic circuit is provided in an enclosure that can efficiently generate magnetic flux from the enclosure, configuring a magnetic disk, to a magnetic disk. Thus, by providing such a magnetic circuit, a magnetic field different from that in other enclosure parts, that is, a local magnetic field, is generated from the magnetic circuit in case the disk device is set in an external magnetic field. Hence, this local magnetic field can effectively erase data in the magnetic disk. In particular, since the local magnetic field is generated even if the external magnetic field is weak, it is possible to not only suppress the demagnetization of permanent magnets used in the spindle motor at minimum, but also effectively erase data in the magnetic disk.
摘要翻译：在外壳中提供磁路，其可以有效地从壳体产生磁通量，将磁盘配置到磁盘。因此，通过设置这样的磁路，在将磁盘装置设定在外部磁场的情况下，从磁路产生与其它外壳部分不同的磁场，即磁场。因此，该局部磁场可以有效地擦除磁盘中的数据。具体地说，由于即使外部磁场较弱也产生局部磁场，所以不仅可以抑制主轴电动机中使用的永久磁铁的退磁至少，还可以有效地擦除磁盘中的数据。

摘要： Embodiments of the present invention provide a rotating disk storage device having a mechanism to reliably retract an actuator into a retraction area in the event that the power supply is suddenly interrupted. A bias chip is embedded in a coil support that supports the voice coil. When a head stays in an access area, the bias chip is away from an end of the voice coil magnet. Therefore, no influence of the magnetic leakage flux is exerted on the bias chip. When the head is in a retraction area, the bias chip is attracted under the influence of the magnetic leakage flux of the voice coil magnet, which thereby produces bias torque causing an actuator to pivotally move in a retraction direction. Accordingly, the bias torque can be utilized as energy for retracting the actuator immediately after power shutdown.
摘要翻译：本发明的实施例提供了一种旋转盘存储装置，其具有在电源突然中断的情况下将致动器可靠地缩回到缩回区域的机构。偏置芯片嵌入在支持音圈的线圈支架中。当头部停留在通路区域时，偏置芯片远离音圈磁铁的一端。因此，不会对偏置芯片施加磁漏磁通的影响。当头部处于退避区域时，偏置芯片在音圈磁体的磁漏磁通的影响下被吸引，由此产生使致动器沿回缩方向枢转运动的偏置扭矩。因此，偏置扭矩可以用作在停电后立即回缩执行器的能量。

摘要： A hard disk drive has an enclosure with disk construction members and is characterized by covering the enclosure with an electrically conductive sheet. The electrically conductive sheet protects the drive regardless of which direction an ESD charge is applied. The electrically conductive sheet does not permit ESD to pass through the disk construction members stored in the enclosure. Therefore, it is possible to form a structure in which a GMR head or the like in an enclosure is not damaged due to ESD even if the enclosure is handled by a general end user. Moreover, the present invention relates to an electrically conductive sheet for covering at least both principal planes of the enclosure of a hard disk drive constituted as described above. Other modes of the invention include at least both principal planes of an enclosure being covered by the electrically conductive sheet in such a way that both sheets on both principal planes are electrically connected. In addition, portions where the enclosure contacts the disk construction members on both principal planes may also be covered and electrically interconnected. Furthermore, the electrically conductive sheet may be bonded to the surface of the enclosure by an adhesive, or provided with an opening at a position corresponding to an enclosure portion that must be brought into contact with an external atmosphere.

摘要： An arrangement structure of the printed circuit board and the interface cable connector of a magnetic disk drive for increasing the degree of freedom of the arrangement of a spindle motor, and for minimizing the size of a printed circuit board. An interface cable connector is disposed on the side opposite to the spindle motor, and the printed circuit board is sized so as not to contact with the spindle motor in the height direction. This allows the degree of freedom of the arrangement of the spindle motor to increase. Further, the distance between the interface cable connector and the preamplifier connector on the printed circuit board is short. Thus, the size of the printed circuit board can be made as small as possible.

摘要： A disk drive. The disk drive includes: a head for accessing a data recording area of a disk; an actuator for pivoting to move the head; a voice coil motor; and, a latch configured to lock the actuator from pivoting toward the data recording area in response to an external force. The voice-coil motor includes a voice coil, a magnet, and a yoke. The latch is positioned at a closed position when the actuator is positioned at a stand-by position, and is configured to pivot by application of a magnetic bias force with pivoting of the actuator from the stand-by position into proximity with the data recording area such that the latch is configured to stop at an open position. The yoke includes a protrusion which protrudes toward the magnetic body at the open position.

摘要： Embodiments of the present invention provide a structure of a pivot receiving surface which may excellently adjust the attitude of a head supporting mechanism in a magnetic disk drive. In one embodiment, three projections are formed at a base for supporting a pivot assembly. The first projection is formed on a first line which bisects an angle defined between a second line and a third line determining a range, in which a head/slider flies above a magnetic disk. In contrast, the other two projections are formed at positions apart from the first projection at an angle of 120°, respectively. The attitude of the pivot assembly is adjusted by adjusting the heights of the projections, and thus, a head supporting mechanism is corrected in a predetermined attitude within the range in which the head/slider flies above the magnetic disk.
