摘要： The present invention provides an improved magnetic data storage and retrieval system, which can absorb external shock and is easily attached to a host system. By setting bumpers in the four corners of a magnetic data storage and retrieval system, external shock can be absorbed to prevent a magnetic disk from being displaced from the proper alignment with its spindle motor. With this arrangement, in the two corners on the end portion side of a guide groove formed in the base, pedestal surfaces are formed in one side of the guide groove, and plate-like bumpers and are set on the pedestals. Further, in the remaining two corners, insertion-type bumpers may be set and a label covering part of them may be affixed.

摘要： Deformation due to thermal shrinkage of a shock absorbing member surrounding a main part of a disk drive-is reduced. In one embodiment, a frame bumper covers a case (base plate) included in a disk drive excluding part of the case provided with a connector. A curved flexible part is formed in a part, opposite the connector, of the frame bumper. The curved flexible part extends or contracts to absorb the deformation of the frame bumper due to thermal shrinkage. The curved flexible part is formed in a substantially middle part of a cross part extending between side parts provided with slots. Slits are formed above and below, respectively, of the curved flexible part to enable the frame member to deform upward and downward relative to the flexible part.

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 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： 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.

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.
