  • Dual stripe read head with magnetic support structures which provide a uniform magnetic field for stabilization during manufacture
    Patent number: 6842312
    Abstract: A method for stabilizing magnetic domains in dual stripe magnetic read heads is provided. This method first comprises providing a plurality of coupled magneto-resistive read elements in a spaced relationship. These read elements include top and bottom patterned magnetic shields on ceramic substrates, with two magneto-resistive (MR) sensor elements between the shields, all separated by insulating layers. Magnetic support structures are provided adjacent and separated from the coupled read elements, wherein the magnetic support structures provide a uniform magnetic field that stabilizes the magnetic domains of the MR sensors in the coupled read elements.
