Method for shaping air bearing surface of magnetic head slider and manufacturing method of magnetic head slider

A method for shaping an air bearing surface of a magnetic head slider, comprising the steps of:

• holding at least one row bar with a plurality of aligned thin-film magnetic head elements by adhering a first surface of said at least one row bar to an adhesive tape capable of passing a laser beam there through, said first surface being opposite to an air bearing surface of said at least one row bar;
• cutting said at least one row bar into individual magnetic head sliders so that said adhesive tape holds all of the individual magnetic head sliders;
• shaping an air bearing surface of said individual magnetic head slider in a convex shape by radiating a laser beam to the first surface of said magnetic head slider through said adhesive tape;
• and
• then, removing the magnetic head sliders from said adhesive tape after weakening adhesion properties of said adhesive tape.
