The hermetically resealable HDD includes a disk enclosure (DE), a magnetic-recording disk, a head-slider, an actuator, a low-density gas, a through-hole, and a plug. The DE includes a base, and a first cover and a second cover joined to the base. The second cover is disposed above the first cover. The through-hole is configurable for injection of a low-density gas into the DE. The low-density gas, having a density less than air, substantially fills the DE. The plug is press-fitted into, and hermetically seals, the through-hole. The plug is removable to allow recharging the DE with the low-density gas; and, the through-hole is configured to accept a resealing plug to be press-fit into, and to reseal hermetically, the through-hole after recharging. A method for injecting low-density gas into, and sealing, the hermetically resealable HDD is also provided.

摘要： A magnetic disk apparatus capable of reducing deformation of a magnetic disk is disclosed. The magnetic disk apparatus comprises a magnetic disk on which data is recorded while the disk is driven, a hub around which the magnetic disk is supported from an under side of the magnetic disk, and a clamp in contact with the other side of the magnetic disk and fixing the magnetic disk. An O-ring is interposed between a flange formed at an outer circumference of the hub and the magnetic disk, and a spacer is interposed between the magnetic disk and the O-ring. Thus an upper surface of the hub is in contact with an under surface of the clamp and defines a vertical position of the magnetic disk.

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.
