  • Publication number: 20020089795
    Abstract: A magnetic recording head includes a current perpendicular to the plane read head having a read sensor and a low resistance lead structure. The lead structure includes a layer of conductive material that forms at least a portion of the lead structure such that the layer of conductive material has a lower resistivity than a resistivity of the remainder of the lead structure. The layer of conductive material with lower resistivity decreases the overall resistance of the lead structure.

  • Publication number: 20020075611
    Abstract: A read head, particularly suitable for a magnetic disc storage system, includes a read sensor having an air-bearing surface and an opposing top surface. The read head also includes a permanent magnet positioned adjacent the top surface of the read sensor for generating a magnetic bias field in the read sensor. The permanent magnet has a magnetization in a direction other than normal to the air-bearing surface of the read sensor.

  • Patent number: 6021802
    Abstract: A device for connecting at least a discharge tube and return tube to a bung connection of a container for liquids and the like, said connection being embodied with inner screw thread, which device comprises a cylindrical insert with screw thread arranged on the cylinder outer wall and co-acting with the bung, in addition to a bottom provided with at least two openings, a tube connecting bung for placing with the lower surface on this bottom and provided with passages for the discharge tube and return tube aligned with these openings, and a clamping piece for fixing the connecting bung in the cylindrical insert via connectors wherein there are arranged lugs placed in a determined pattern and recesses receiving these lugs, wherein the clamping piece is connected non-slidably in axial direction to the bung but freely rotatable relative thereto, and wherein the connectors in the insert are arranged at a distance from the bottom in order to form a chamber, the recesses are placed above the chamber in the insert an
