Abstract:
A magnetic head in one embodiment includes a pole; a first write gap in the pole; a first coil for generating a magnetic flux across the first write gap; a second write gap in the pole having at least a portion thereof aligned with the first write gap in a direction parallel to a direction of media travel thereover; and a second coil for generating a magnetic flux across the second write gap, the second coil being addressable independently of the first coil. A method in one embodiment includes forming a first write coil; forming a first write gap; forming a second write gap; forming a second coil for generating a magnetic flux across the second write gap, the second coil being addressable independently of the first coil; and forming one or more write poles, wherein a write pole region adjacent the first and second write gaps is formed concurrently.
