Embodiments include a method for adjusting the twist of an air bearing surface of at least one slider to substantially match a target values for twist, the at least one slider having a back surface opposite the air bearing surface, the back surface including two sets of diagonally opposite comer regions, with each set including one comer region adjacent to a leading edge of the slider and one comer region adjacent to a trailing edge of the slider. The method includes forming a first mechanical scribe on the back surface extending through at least a portion of the corner regions adjacent to the leading edge of the slider and forming a second mechanical scribe on the back surface extending through at least a portion of the comer regions adjacent to the trailing edge of the slider. The method also includes measuring the twist of the slider, and forming a first group of laser scribes on the back surface in one of the two sets of diagonally opposite comer regions, wherein each of the laser scribes intersects with one of the first and second mechanical scribes. The method also includes measuring the twist of the slider and comparing the values to the target value for twist, and forming additional laser scribes if the target value for twist is not reached.
