    Abstract: A recording head that includes a reader having a front end at a bearing surface of the recording head and a rear end behind the bearing surface. The reader has a non-rectangular shape with a front-end width that is less than an average width of the reader. A first bias element is positioned proximate to a first side of the reader, and a second bias element is positioned proximate to a second side of the reader. Each of the first and second bias elements has a bias level that is a function of a ratio of the front-end width to the average width of the reader.
