Abstract
In one embodiment, a magnetic head includes a main magnetic pole, a trailing shield positioned on a trailing side of the main magnetic pole, a trailing gap positioned between the trailing shield and the main magnetic pole, side shields positioned on either side of the main magnetic pole in a cross-track direction, side gaps positioned between the side shields and the main magnetic pole on either side of the main magnetic pole in the cross-track direction, and trailing shield gaps positioned on either side of the main magnetic pole in the cross-track direction between the trailing shield and the side shields, wherein the trailing shield gaps extend beyond the side gaps in a direction parallel to the cross-track direction. In addition, a method for producing a magnetic head as described above is also disclosed, according to one embodiment.
