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： Embodiments of the invention permit a magnet-based actuator lock mechanism to operate smoothly in a magnetic disk drive that uses a base made of a magnetic material. In one embodiment, the base to be used is made of a magnetic material. The actuator lock mechanism includes a rotatable arm that retains a magnet. A magnetic attraction force, which is oriented toward the base as indicated by an arrow, is generated in the magnet. The base is provided with a cut to reduce the attraction force. The cut is covered with a sealing material to maintain internal airtightness. The actuator lock mechanism may be, for instance, an eddy-current latch, inertia latch, or magnetic latch.

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： A magnetic disk drive is to be provided wherein a ramp and a magnetic disk do not overlap each other and both rigidity and dynamic characteristics of a suspension are maintained. In one embodiment, a ramp and an actuator lying at a retractive position are spaced away from and do not overlap an outer peripheral end of a magnetic disk. A tab is formed centrally of a front end of a load beam and is bent in U shape. Flanges are formed along both longitudinal edges of the load beam. An aperture is formed in a front portion of the load beam. The aperture permits the tab to be machined in a desired shape. An aperture is formed behind the aperture. The apertures are not formed in an integrally contiguous manner but are separated from each other by a bridge portion.

摘要： A bearing structure used in a pivot bearing for freely supporting the rotation of a head arm of a hard disk drive (HDD). The bearing structure includes an inner shaft, an outer sleeve, a pair of roller bearings axially spaced and interposed between the inner shaft and the outer sleeve, and a preload spring for exerting a preload on the roller bearings. The roller bearings may be provided with an outer race that is attached to the outer sleeve. Nevertheless, the coefficients of linear expansion of the inner shaft and the outer sleeve are chosen so that they are different in an axial direction. Accordingly, the coefficients of linear expansion of the inner shaft and the outer sleeve are chosen so that the rotation torque derived from the preload becomes higher as the temperature rises and lower as the temperature falls. However, the rotational torque becomes lower as the temperature of a lubricant rises and higher as the lubricant temperature falls. Thus, the changes in the rotational torque as a result of temperature change are cancelled out.
摘要翻译：一种用于枢转轴承的轴承结构，用于自由地支撑硬盘驱动器（HDD）的头臂的旋转。轴承结构包括内轴，外套筒，轴向间隔开并置于内轴和外套筒之间的一对滚子轴承，以及用于在滚柱轴承上施加预载荷的预载弹簧。滚子轴承可以设置有附接到外套筒的外圈。然而，选择内轴和外套筒的线性膨胀系数使得它们在轴向方向上不同。因此，选择内轴和外套筒的线性膨胀系数，使得从预压力导出的旋转扭矩随温度随温度升高而降低。然而，随着润滑剂的温度升高，旋转扭矩变低，随着润滑剂的温度下降，转矩越高。因此，由于温度变化导致的转矩的变化被抵消。

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.
