摘要： Embodiments in accordance with the present invention relate to greatly decreasing vibrations of a rotary disk at a portion where vibration on the disks is to be suppressed in a vibration-suppressing mechanism for rotary disks while enabling the rotary disks to be incorporated in the shroud surface. In one embodiment, the vibration-suppressing mechanism for rotary disks comprises at least one of rotary disk and a shroud surface extending along and facing the outer circumferential edges of the disk. The shroud surface is so formed as to possess a portion where a gap between the outer circumferential edge of the disk and the shroud surface becomes small near a portion where the vibration of the disk is to be suppressed.

摘要： A removable cover assembly for a data storage device comprises a first cover coupled with a casing base of a data storage device via a plurality of screws. A second cover is disposed upon a rib of the casing base and is coupled with the rib. The second cover is configured with a groove which delineates a perimeter separating an interior region of the second cover from an exterior region of the second cover. A space between the first cover and the casing base is filled with a low-density gas. The groove defines the region in the second cover in which separation of the interior region from the exterior region is to occur to expose the screws.

摘要： Embodiments of the invention provide a magnetic disk device capable of improving the shielding function for the magnetic head yet maintaining a form factor. In one embodiment, a magnetic disk device comprises a magnetic disk; a magnetic head for recording/reproducing information; a magnetic disk drive mechanism for moving magnetic head in the radial direction of the magnetic disk; a housing including a base and a cover having a nonmagnetic material; and a magnetic shielding member having a magnetic material. The housing has a cut-away portion corresponding to a range in which the magnetic head moves, and the magnetic shielding member is formed in a U-shape including an upper wall portion, a side wall portion and a bottom wall portion. The magnetic shielding member covers the range in which the magnetic head moves, and is disposed in the cut-away portion so as to form substantially the same surface as the surfaces of the upper wall, side wall and bottom wall of the housing.

摘要： In a hard disk drive, for the purpose of solving a problem that a mass of the tip of a VCM actuator increases, a primary resonance frequency lowers and a control band lowers in a case where a balance driving mechanism which damps a vibration during the driving of a microactuator is mounted, a damping unit using a displacement enlargement mechanism by resonance is disposed to obtain a sufficient damping effect with a small mass, thereby setting a resonance frequency of the damping unit to be higher than a frequency of a resonance peak of a damping object. The hard disk drive includes a micromotion actuator for micromotion displacement which drives a head-gimbal assembly, and a micromotion actuator for damping which drives the damping unit so that the micromotion displacement direction of a magnetic head and the displacement direction of a mount portion have opposite phases.
