摘要： When a cover is joined with the base of a magnetic disc drive by welding, bubbles in the die casting suddenly expand due to high temperature at the time of welding and blow off fused metal, and a blowhole occurs. Low density gas sealed up in a casing is liable to easily leak through a leak path made by joining of blowholes. Embodiments of the present invention provide a joint structure of a base and a cover so that helium does not easily leak through the blowholes by filling low density gas such as helium gas in a disc drive so as to be capable of sealing for a long period of time. According to one embodiment, after assembly of a magnetic disc drive, the magnetic disk drive is put into a basket and sent in a vacuum container containing low vapor pressure oil. After that, the vacuum container is vacuumed, and the magnetic disc drive put in the basket is immersed in low vapor pressure oil, and a valve is opened to make the vacuum container atmospheric pressure condition. By the change of the condition from vacuum to atmospheric pressure, low vapor pressure oil gets into a leak path. Since helium is dissolved in low vapor pressure oil, diffuses in the oil, and moves in the leak path, the passing speed conspicuously lowers.

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.

摘要： Embodiments of the present invention allow a cover of a magnetic disk drive to be temporarily joined to a base without widening a mounting space, and completely joined after a head disk assembly (HDA) inspection. According to one embodiment, a cover includes a metal plate, an adhesive, and a seal member. The adhesive has a surface wider than the metal plate and the seal member has a surface wider than the adhesive. A solder is coated or printed at an outer periphery of the seal member. A gasket is set at a flange of a base sidewall and an outer peripheral portion of the adhesive of the cover is affixed to an upper surface of the base sidewall to temporarily fix the cover. Low-density gas is injected in a casing interior and a functional inspection of the HDA is performed. After the inspection is finished, helium is injected again, and the casing is completely sealed by melting the solder of the seal member, and joining the seal member to a collar-shaped protrusion of the base sidewall by the solder.

摘要： A disk drive includes a head for accessing a disk, a suspension for supporting the head, a carriage coupled to the suspension, a pivot-bearing assembly, an adhesive, and an adhesion inhibitor. The pivot-bearing assembly is housed in a hole of the carriage that is configured to rotate in such a way that the carriage is configured to oscillate. The adhesive is disposed between the pivot-bearing assembly and an inner circumferential surface of the hole for bonding the pivot-bearing assembly with the carriage. The adhesion inhibitor is disposed on the same surface as the adhesive for controlling a region of adhesion.

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.
