  • Supermalloy and Mu Metal Side and Top Shields for Magnetic Read Heads
    Publication number: 20140315045
    Abstract: The use of supermalloy-like materials for the side and top shields of a magnetic bit sensor is shown to provide better shielding protection from stray fields because of their extremely high permeability.

  • CPP Device with Improved Current Confining Structure and Process
    Publication number: 20130088797
    Abstract: Plasma nitridation, in place of plasma oxidation, is used for the formation of a CCP layer. Al, Mg, Hf, etc. all form insulating nitrides under these conditions. Maintaining the structure at a temperature of at least 150° C. during plasma nitridation and/or performing post annealing at a temperature of 220° C. or higher, ensures that no copper nitride can form.
