  • Patent number: 8760797
    Abstract: Various aspects of the present disclosure are directed toward a disc drive apparatus having an inner enclosure structure that resides within an outer disc drive enclosure. The inner enclosure structure includes an environment-adsorption material, an inner volume of gas, and an aperture-defining membrane. The environment-adsorption material combines a first-type of molecules with a second-type of molecules that are present in the outer disc drive enclosure. Additionally, the aperture-defining membrane facilitates diffusion of the second-type of molecules into the inner enclosure structure and into contact with the environment-adsorption material to adsorb the second-type of molecules into the first-type of molecules, which reduces the volumetric pressure in the outer disc drive enclosure.

  • Publication number: 20090188386
    Abstract: Methods of controlling relative humidity in an enclosure that include preparing an aqueous solution, the aqueous solution including a hydratable salt, the hydratable salt including a divalent cation; preparing a second composition, the second composition including the aqueous solution; and polyacrylamide, a copolymer of polyacrylic acid and polyacrylamide, or both; and placing the second composition in the enclosure, wherein the second composition absorbs water from the atmosphere of the enclosure. Devices and systems including desiccants are also disclosed.

  • Patent number: 6549367
    Abstract: The performance of a leaf spring disc clamp can be enhanced by utilizing a roughly triangular shape for the center aperture. Such a disc clamp exhibits a substantially more uniform distribution of clamping force on the data disc and thereby reduces the deformation of the disc. It has further been determined that a stiffening rib located adjacent to the rim portion which contacts the data disc also leads to more uniform distribution of clamping force. Lastly, vibrations in a leaf spring disc clamp from external shocks or drive operation can be reduced utilizing a dampening ring of visco-elastic material. The dampening ring can be fastened to the surface of the disc clamp or placed within a rib on the disc clamp.

  • Patent number: 6317286
    Abstract: An apparatus for minimizing corrosion product build-up within a disc drive incorporates a non-corrosive gas hermetically sealed within the disc drive and a diaphragm chamber that allows the constrained non-corrosive gas to respond to changes in pressure and temperature. The diaphragm chamber includes a diaphragm that partitions the diaphragm chamber into a top and bottom chambers. The top chamber has an aperture for communicating with the external environment and the bottom chamber has an aperture for communicating with the internally constrained non-corrosive gas. The diaphragm is non-permeable and made of an elastic material that responds to changes in air volume or mass on either side of the partition so that the pressure inside the hermetically sealed disc drive is constant throughout the life of the device. The diaphragm chamber can be located inside or outside the disc drive and can be integrally formed within the top cover of the disc drive.
