Abstract:
1. A method for manufacturing sliders from a bar, wherein elements and spaces are alternately arranged in said bar, said elements being formed into said sliders, and said spaces being used to dice said bar into said sliders, the method comprising: a radiating step which includes radiating an electromagnetic wave on at least a part of each space on a second surface of said bar, wherein said second surface is a back surface of a first surface of said bar, said first surface being formed into an air bearing surface of said slider, wherein said space is sandwiched between said elements, and wherein said electromagnetic wave is radiated such that an entire portion of said bar forms a curved shape such that said first surface forms a convex surface; a lapping step that is performed after the radiating step, the lapping step including lapping said first surface while pressing said bar against a lapping surface such that said first surface of each element forms a concave shape; and a dicing step that is performed after the lapping step, the dicing step including dicing said bar along said spaces to separate said bar into said sliders.
