ABSTRACT:
A method for shaping an ABS of a magnetic head slider including a step of holding at least one row bar with a plurality of aligned thin-film magnetic head elements by adhering a first surface of the at least one row bar to an adhesive or UV tape capable of passing a laser beam there through, the first surface being opposite an ABS of the at least one row bar, a step of shaping the ABS of the at least one row bar in a convex shape by radiating a laser beam to the first surface of the at least one row bar through the adhesive or UV tape, a step of cutting the at least one row bar into individual magnetic head sliders, and a step of then, removing the magnetic head sliders from the adhesive or UV tape after weakening adhesion properties of the adhesive or UV tape.
