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.

A magnetic head, comprising:
- 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, comprising:
- 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.
A method, comprising:
- forming a lower shield of a shield structure;
- forming a portion of a magnetic yoke for each of at least two write transducers above the lower shield of the shield structure;
- and
- forming an upper shield of the shield structure above the portions of the yokes of each of two of the at least two write transducers, the shields being formed of a magnetically permeable material, wherein the upper and lower shields are magnetically connected.
