According to one embodiment, a method includes tracking a magnetic tape moving in a first direction using at least one reader of an inner module of a head having at least the inner module and first and second outer modules positioned on opposite sides of the inner module and aligned with the inner module in a tape travel direction, detecting a signal using at least one reader of the first outer module as the tape passes thereacross, moving a guide positioned in front of the first outer module in a direction towards the tape until the signal detected by the first outer module decreases by a predetermined amount, and moving the guide directionally away from the tape to a position to set about a predetermined wrap angle of the tape relative to the first outer module after the signal detected by the first outer module decreases by the predetermined amount.
