    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 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： In a disk drive device having a double cover structure with low-density gas enclosed therein, embodiments of the present invention help to securely perform leak inspection on an outer cover and to prevent defects caused in joining the outer cover. According to one embodiment, a hard disk drive (HDD) comprises a flow amount adjuster on a base-facing side of its inner cover. Helium gas in an enclosure goes out through a ventilation hole via diffusion channel of a flow amount adjuster. The emitted helium gas remains in the space between the inner cover and an outer cover. This achieves easier detection of the leakage of helium gas from the joining section of the outer cover and prevention of emission of too much helium gas from the enclosure.

    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： 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.
