The magnetic recording medium of the invention preferably includes a Co or Co alloy film magnetic layer, and Mn-containing layer, preferably comprised of VMn, TiMn, MnZn, CrMnMo, CrMnW, CrMnV, and CrMnTi, and most preferably a CrMn alloy, disposed between the substrate and the magnetic layer to promote an epitaxial crystalline structure in the magnetic layer. The medium can further include seed layers, preferably polycrystalline MgO for longitudinal media, underlayers, and intermediate layers. Underlayers and intermediate layers are comprised of materials having either an A2 structure or a B2-ordered crystalline structure disposed between the seed layer and the magnetic layer. Materials having an A2 structure are preferably Cr or Cr alloys, such as CrV, CrMo, CrW and CrTi.

    摘要: The present invention provides for magnetic and magneto-optic recording media, transducers and data storage devices constructed therefrom that have highly oriented films having long range order in the crystal structure of the film. The recording medium includes a magnetic recording layer comprised of Co-based material, such as Co or one or more Co alloys having a (10{overscore (1)}0) crystal texture, a substrate, a first underlayer having a fcc structure and a (110) crystal texture disposed between the substrate and the magnetic recording layer. A second underlayer having a bcc structure and a (112) crystal texture is also disposed between the magnetic recording layer and the first underlayer. In particular, if a (110) Si single crystal substrate is non-oxidized certain metals having fcc structures, such as Ag, Cu, Al, and Au and fcc derivative structures, such L10 and L12 structures, can be epitaxially grown on the Si surface. While the one unit cell to one unit cell lattice match between fcc Ag and A4 (diamond) Si is quite poor, multiples of the Ag unit cell distance fit very well on the Si surface. The long range order of the Si surface induces the epitaxial growth of the Ag fcc structure. Upon this fcc structure, a bcc structure, such as Cr, or a bcc derivative, such as B2, DO3 and/or L21 can be epitaxially grown.

    摘要: A cabinet dehydrator for home preservation of food under relative humidity, pressure, and temperature restraints. Intake air is obtained from the surrounding atmosphere and displaced into the dehydrator over heating elements by a blower. This heated air is ported through a manifold defined by the cabinet walls having a sloping chamber which narrows toward the top of the cabinet to evenly displace the heated air over the tops of removable drying trays. The heated air withdraws moisture from the articles of food placed on the drying trays, and is partially exhausted through exhaust portals, depending upon the relative humidity, temperature, and pressure of the surrounding atmosphere. The remaining heated air is mixed with an amount of surrounding air entering through intake portals to replace the amount exhausted. This mixture of heated air and intake air is then heated and recirculated by the blower until the articles of food are dried.
