Abstract
Embodiments of the present invention provide a method for manufacturing a magnetic disk unit, the method permitting easy and efficient introduction of a low-density gas into the enclosure. According to one embodiment, an enclosure of the magnetic disk unit has a gas inlet and a gas outlet, each of which is provided with a filter. When the enclosure is filled with helium, the mass flow rate of helium being supplied to the gas inlet is detected and the mass flow rate of helium being supplied to the gas inlet is controlled according to the thus detected mass flow rate of helium.
