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.

摘要： When a cover is joined with the base of a magnetic disc drive by welding, bubbles in the die casting suddenly expand due to high temperature at the time of welding and blow off fused metal, and a blowhole occurs. Low density gas sealed up in a casing is liable to easily leak through a leak path made by joining of blowholes. Embodiments of the present invention provide a joint structure of a base and a cover so that helium does not easily leak through the blowholes by filling low density gas such as helium gas in a disc drive so as to be capable of sealing for a long period of time. According to one embodiment, after assembly of a magnetic disc drive, the magnetic disk drive is put into a basket and sent in a vacuum container containing low vapor pressure oil. After that, the vacuum container is vacuumed, and the magnetic disc drive put in the basket is immersed in low vapor pressure oil, and a valve is opened to make the vacuum container atmospheric pressure condition. By the change of the condition from vacuum to atmospheric pressure, low vapor pressure oil gets into a leak path. Since helium is dissolved in low vapor pressure oil, diffuses in the oil, and moves in the leak path, the passing speed conspicuously lowers.
摘要翻译：当通过焊接将盖与磁盘驱动器的基座连接时，由于焊接时的高温和熔融金属的吹出，压铸件中的气泡突然膨胀，并且产生气孔。密封在壳体中的低密度气体易于通过通过连接气孔而形成的泄漏路径泄漏。本发明的实施例提供了一种基座和盖子的接头结构，使得氦气通过在盘驱动器中填充诸如氦气之类的低密度气体而不易通过气孔泄漏，以便能够长时间地密封时间。根据一个实施例，在组装磁盘驱动器之后，将磁盘驱动器放入筐中并送入含有低蒸汽压力油的真空容器中。之后，将真空容器抽真空，放入篮中的磁盘驱动器浸入低蒸汽压力油中，打开阀门使真空容器大气压条件。通过将条件从真空变为大气压，低蒸气压油进入泄漏路径。由于氦溶解在低蒸气压油中，在油中扩散并在泄漏路径中移动，通过速度显着降低。

摘要： 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.
