摘要： A working method capable of implementing various types of devices such as a slider available with high reliability without causing malfunction or the like due to contamination during an actual use is provided by solving a problem of deterioration in profile precision and a problem of contamination resulting from roughness of a cut surface or chipping. A wire saw comprising a wire having a diameter greater than a width of a portion cut by a first cutting step, namely, a width of a cut groove is brought into contact with the cut groove of a bar. While the wire saw is slid in a longitudinal direction, the bar is sliced across the overall thickness of the bar along the thickness of the bar. Thus, while the bar is cut, a final cut surface formed by cutting is smoothed.

摘要： To provide a manufacturing method which can adjust the lengths of a recording element and a reproducing element for enabling manufacture of high-quality magnetic head sliders. The manufacturing method comprises: a stacked-layer forming step which stacks magnetic heads on a substrate; a lapping step which cuts out a bar block having a plurality of connected magnetic head sliders, and polishes a flying surface; and a slider cutting step which cuts out individual magnetic head sliders from the bar block. The stacked-layer forming step forms a reproducing-element polish amount detecting sensor on a same layer as that of the reproducing element, and forms a recording-element polish amount detecting sensor on a same layer as that of the recording element. The lapping step carries out polishing based on each output value of the reproducing-element polish amount detecting sensor and the recording-element polish amount detecting sensor.
