A humidity control method and apparatus that can be utilized to provide humidity control within an enclosed assembly such as a disc drive. The apparatus includes a container that is at least partially formed of a material through which water vapor can freely move. The apparatus also includes a humidity-controlling mixture that comprises at least one salt and a superabsorbent polymer. The humidity-controlling mixture is enclosed within the container.
What is claimed is: 1. A method for maintaining a relatively constant humidity in an enclosure, the method comprising: preparing a saturated aqueous solution of at least one salt; introducing excess solid of the same at least one salt in intimate contact with the saturated aqueous solution; and adding a super-absorbent polymer to contain both the saturated aqueous solution and the excess solid and to adsorb a puddle that may be formed when the saturated aqueous solution and the excess solid absorb water, wherein the saturated aqueous solution, the exces...
