Abstract: A sound-attenuation part, such as for use in a rack-mount server, is configured for insertion into an orifice of a backplane to which at least one data storage device is coupled. The sound-attenuation part may include one or more pipes extending from a mounting portion. The sound-attenuation part helps to attenuate acoustic noise, such as from a cooling fan, which might otherwise reach the data storage device, such as through airflow orifices constituent to a backplane that is positioned between the fan and the storage device, while maintaining enough airflow through the backplane for system cooling purposes. Thus, degradation of the head positioning accuracy within the storage device, caused by the forces associated with this acoustic noise, may be reduced.

Abstract: A data storage device (DSD) is assembled with a flexible sheet of barrier material covering at least a portion of the top cover and/or bottom base of the DSD enclosure, whereby a layer of air is between the sheet of barrier material and the cover and/or base. Polyvinlyidene chloride (PVDC) may be used as the barrier material.

Abstract: Embodiments of the present invention help to provide a magnetic disk drive in which the base and the lid are securely welded together, so that the low-density gas sealed therein is protected from leakage. According to one embodiment, the peripheral surface of the rib of the base is machined to form the surface, which is free of electrocoating and weld surface. The outer lid, which completely conforms to the contour of the base, is placed on the rib, and the laser beam is directed onto the outer lid. Thus the position of laser beam irradiation varies within only ±0.05 mm for both the base and the lid. Laser welding in this manner yields the bead invariably, which makes the enclosure completely sealed without helium leakage.
