ABSTRACT:
A magnetic head comprises a plurality of elements selected from a group consisting of readers and writers. A servo sensor is positioned towards the elements, the servo sensor being adapted for sensing a first servo track of a magnetic medium. A fence is positioned towards the servo sensor and aligned therewith in a tape travel direction. A magnetic head in another embodiment includes a substrate and a reader positioned above the substrate, the reader having a sensor and shields sandwiching the sensor. A fence is positioned towards the reader on an opposite side thereof from the substrate, the fence being aligned with the reader in a travel direction of a magnetic medium passing thereby.
