ABSTRACT:
In a magnetic memory device wherein a magnetic recording medium is rotated in a substantially closed chamber, there are provided a throttle between the inside and outside of the chamber, a first air fliter for filtering air flowing through the throttle to prevent moisture from entering into the chamber by diffusion, a container containing a desiccating agent and communicated with the chamber, and a second air filter located between the desiccating agent container and the chamber. In a modified embodiment, another throttle is also provided between the desiccating agent container and the substantially closed chamber.
