摘要： Embodiments of the invention provide a disk device capable of diminishing oscillation of a disk caused by an air flow which is created with rotation of the disk. In one embodiment, a magnetic disk device comprises a rotatable magnetic disk, a base and a top cover for housing the magnetic disk inside, a flow uniforming wall disposed along an outer periphery of the magnetic disk, and a circulation filter for collecting dust present within the device. The flow uniforming wall is positioned in opposition to the outer periphery of the magnetic disk and has a step height at a position other than the position opposed to the disk outer periphery, with an opening being formed by a gap between the step height and the top cover. This opening serves as an inlet port to admit an air flow created with rotation of the magnetic disk, and the circulation filter collects dust contained in the admitted air flow.

摘要： Embodiments of the present invention provide a magnetic disk device that can reduce an external force applied to the carriage. According to one embodiment, in a magnetic disk device, a bracket inserted between a carriage and a base is supported toward the base side by support portions owned by the bracket and by a band with a space provided between the bracket and the opposed side of the carriage (such as a top surface of the mounting stand). This configuration cannot apply an external force in the rotation direction to the carriage from the bracket even when the bracket is thermally expanded due to heat generated from a head amplifier or the like mounted on a flexible substrate.

摘要： Embodiments of the invention improve the impact-resisting performance of a disk drive. In a head actuator assembly according to an embodiment of the invention, the difference in resonance frequency between an arm bending mode and a coil bending mode is set at a predetermined value or less. Since there is a phase difference between these two modes, an oscillation gain in the arm bending mode can be greatly decreased by approximating the two resonance frequencies to each other. Consequently, it is possible to suppress collision of a head with a recording disk caused by an external shock and thereby improve the impact-resisting performance of a disk drive.

The main data-storage unit is placed at the rear of the external connector as viewed from the opening. The external connector is joined and secured to the main data-storage unit and the exterior housing. In addition, the elastic shock-reduction part is configured to deform with a movement of the main data-storage unit in the exterior housing produced by a mechanical shock and a movable range of the external connector is smaller than a movable range of the main data-storage unit.
