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.
摘要翻译：本发明的实施例有助于在低密度气体注入盘驱动装置期间防止低密度气体的泄漏并有效地进行低密度气体注入。在根据本发明的一个实施例的硬盘驱动器（HDD）中，具有阀功能的注入孔过滤器附接到氦注入孔，以便在外壳中注入氦气。注入孔过滤器具有构造成在打开状态或关闭状态下操作的阀构件。打开状态是氦气被注入的状态，关闭状态是在氦气被完成注入之后的状态。如果外部压力高于内部压力，则阀构件处于打开状态，并且如果内部压力高于外部压力则处于关闭状态。

摘要： A magnetic disk device including: one or more disk-shaped magnetic disks; a spindle motor; a magnetic head; an arm for supporting the magnetic head; an enclosure base for housing the above components; an adjacent facing surface which lies in the enclosure base adjacent to the magnetic disk; a non-adjacent facing surface which lies in the enclosure opposite the magnetic disk and is further from the magnetic disk than the adjacent facing surface; a connecting surface for connecting the adjacent facing surface and the non-adjacent facing surface; and a groove which extends in the circumferential direction of the magnetic disk on the magnetic disk inner circumferential side of the adjacent facing surface, wherein one end of the groove is exposed at the connecting surface, while the other end has an end face which is perpendicular to the direction of rotation of the magnetic disk.
