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： 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 invention provide a rotating disk storage device including a connection structure between an FPC and a printed board and providing allowance for dimensional tolerances. In one embodiment, the rotating disk storage device includes a disk enclosure, an FPC supporting portion, and a flexible printed circuit board assembly provided with an FPC terminal area that extends along a front surface of the FPC supporting portion and further beyond an end portion of the FPC supporting portion. When the printed board is mounted on the disk enclosure, a connector terminal contacts and gives pressure to an FPC terminal formed in the FPC terminal area. This causes the FPC terminal area to flex in the direction of an arrow.

摘要： A rotating disk storage device has a stopper mechanism and a latch mechanism for diminishing a shock imposed on an actuator head suspension assembly (AHSA) and permits positive retraction of the AHSA upon occurrence of an external shock or runaway. In one embodiment, the latch mechanism comprises an AHSA which is supported pivotably, a stopper which restricts a pivotal movement in a pivot direction of the AHSA, an inertia member adapted to move pivotally in a corresponding pivot direction when the AHSA moves pivotally in the pivot direction while causing the stopper to be deformed elastically, and a latch member which has an engaging portion and which, upon receipt of the torque from the inertia member, moves pivotally in a direction opposite from the corresponding pivot direction, and causes the engaging portion to move to a latching position. Shock energy of the AHSA is attenuated by both stopper and inertia member.

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.
