Abstract
A method for fabricating a magnetic transducer is described. The magnetic transducer includes a pole having a pole tip and a flared region. The method Includes providing a first mask layer on the pole and providing a second mask layer on the first mask layer. The first mask layer is soluble in a predetermined solution and has a first thickness. The second mask layer has a second thickness greater than the first thickness. The method also includes forming a mask from the first mask layer and the second mask layer. The step of forming the mask layer includes using the predetermined solution. The mask has a pattern that exposes a portion of the pole tip and covers a portion of the flared region. The method also includes providing a wrap-around shield on at least the pole tip.
