Abstract: 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.

Abstract: 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.

Abstract: If a large external impact is applied to a magnetic disc apparatus, a slider jumps from a disc surface and rotates. When the slider jumps and rotates, its edges re-contact the disc surface to damage this surface. To reduce the rotation angle of the slider to control its position if an impact is effected, the present invention provides a roof on a load arm to reduce the contact angle at which the slider contacts the disc surface in order to relax the impact upon a contact.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Embodiments of the present invention help to effectively suppress vibration of the disk in a Hard Disk Drive (HDD) with low density gas sealed therein, and securely prevent leakage of the low density gas from the base. In an embodiment, helium gas is sealed in a hermetically sealed enclosure of an HDD, and a shroud is formed integrally with a base. In manufacturing the base, a magnetic disk facing surface of the shroud is shaped by cutting after die-casting. This accomplishes a small and precise size of the gap between the magnetic disk facing surface and the circumferential edge of the disk. Cutting the shroud formed independently from the exterior walls, which ensure the hermeticity with the shroud, suppresses the vibration of the magnetic disk and eliminates the necessity of cutting of the inner surfaces of the exterior walls for the purpose of suppression of the vibration to reduce the risk of helium leakage.
