PROBLEM TO BE SOLVED: To reduce a polishing margin in a wrapping process, according to the shape of a row-bar grinding surface. SOLUTION: The method for manufacturing a magnetic head slider includes: a first grinding step of grinding a first row-bar to form a first grinding surface while maintaining a block by an implement; a step of wrapping the first grinding surface to form a medium facing surface, and cutting the first row-bar from the block; a second grinding step of grinding a second row-bar to form a second grinding surface; and a step of wrapping the second grinding surface to form a medium facing surface. In the first (second) step, the first (second) row-bar is grinding until distances from two reference markers 14 arranged in the first (second) row-bar to the first (second) grinding surface 12 become equal to a first (second) reference distance P1 (P2). Between the grinding steps, a distribution of distances along the longitudinal direction of the first row-bar between a virtual surface S' and the first grinding surface 12 is acquired.
