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 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.
摘要翻译：本发明的实施例有助于有效地抑制密封在其中的低密度气体的硬盘驱动器（HDD）中的盘的振动，并且可靠地防止低密度气体从基座泄漏。在一个实施例中，氦气密封在HDD的气密密封的外壳中，并且护罩与基座一体地形成。在制造基座时，通过在压铸之后的切割来成形护罩的面向磁盘的表面。这实现了磁盘对向表面和盘的圆周边缘之间的间隙的小而精确的尺寸。切割独立于外壁形成的护罩，其确保与护罩的气密性，抑制磁盘的振动，并且消除了为了抑制振动的目的而切割外壁的内表面的必要性，以减少氦气泄漏的危险。

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.
