摘要： In a magnetic disc apparatus, it is hard to fix a pivot mechanism in a carriage, in view of a mounting space, and in the case that a casing is made of resin, it is hard to fix in accordance with a conventional screwing method in view of a rigidity and a strength. A pivot mechanism (107) is fixed to a base (100) by press fitting a plastically deformable pivot pin (108) of the pivot mechanism (107) to the base (100), passing the pivot pin (108) through a sleeve (107-a) of the pivot mechanism (107) and plastically deforming the pivot pin (108). In the case of dissembling, the pivot pin (108) is pushed out from the base (100) together with a carriage (104), and thereafter the pivot pin (108) is separated from the pivot mechanism (107). Only the pivot pin (108) is disposable.

摘要： A magnetic disk apparatus capable of reducing deformation of a magnetic disk is disclosed. The magnetic disk apparatus comprises a magnetic disk on which data is recorded while the disk is driven, a hub around which the magnetic disk is supported from an under side of the magnetic disk, and a clamp in contact with the other side of the magnetic disk and fixing the magnetic disk. An O-ring is interposed between a flange formed at an outer circumference of the hub and the magnetic disk, and a spacer is interposed between the magnetic disk and the O-ring. Thus an upper surface of the hub is in contact with an under surface of the clamp and defines a vertical position of the magnetic disk.

摘要： Embodiments of the present invention help to prevent leakage of low-density gas during low-density gas injection into a disk drive device and to perform low-density gas injection efficiently. In a hard disk drive (HDD) according to one embodiment of the present invention, an injection hole filter with a valve function is attached to a helium injection hole in order to inject helium gas in an enclosure. The injection hole filter has a valve member configured to operate in an open state or closed state. The open state is a state while the helium gas is being injected and the closed state is a state after the helium gas has been finished to be injected. The valve member is in the open state if the outside pressure is higher than the inside pressure and is in the closed state if the inside pressure is higher than the outside pressure.

摘要： Embodiments of the present invention provide a simpler, miniaturizable, and highly reliable hermetically sealed enclosure structure in a disk drive device. According to one embodiment, a hard disk drive (HDD) comprises an HDD main unit, a case for housing the HDD main unit, a lid with a feedthrough function for closing an opening of the case, and an FPC connector for interconnecting the HDD main unit and a plurality of pins fixed to the lid. The lid is joined to the case and completely closes the opening of the case. The case and the lid form a sealed enclosure; the internal HDD main unit is housed in the sealed space. Housing the HDD main unit in a sealed space may increase resistance of the HDD to external environmental changes. Sealing low density gas like helium in the sealed space may improve the performance of the HDD.

摘要： In a disk drive device having a double cover structure with low-density gas enclosed therein, embodiments of the present invention allow a more reliable leak inspection to be performed on the second cover and to prevent defects caused by joining the secondary cover. An HDD according to an embodiment of the present invention comprises a ventilation path from a ventilation hole on an inner cover to a space between the inner cover and an outer cover. An outer peripheral end of an adhesive layer is apart from a joining section, which is exposed in the space. Helium gas flowing out of the ventilation hole flows to the space via the ventilation path and remains within the space. This enables detection of leakage of the helium gas from the joining section to be performed more easily.

摘要： Embodiments of the present invention provide a magnetic disk drive with an enclosure that prevents the low-density gas from leaking out owing to reduction of shrinkage cavities near tapped holes. According to one embodiment of the present invention, an aluminum alloy is forced into the region of the base in which the tapped hole is to be made, by squeezing in the final stage of die casting to form the base. This procedure increases the density of aluminum alloy above 2.7 g/cm3, and the densified aluminum alloy in the region for tapped holes, is free of shrinkage cavities that can cause gas leakage.
