Abstract:
A magnetic head according to one embodiment includes at least two write transducers for writing to a magnetic medium; and a shield structure having at least two magnetically connected shields which at least partially cover two opposite sides of the writer. A magnetic head according to another embodiment includes at least two write transducers for writing to a magnetic medium, the at least two write transducers being positioned adjacent each other and aligned along a line; and a shield structure having shields adjacent at least three sides of each of the at least two write transducers, the shields being formed of a magnetically permeable material. Additional devices, systems, and methods are also presented.
