Abstract
A row of magnetic read/write sliders which have scribe lines on a back surface. The scribe lines provide an accurate curvature for the air bearing surface which is opposite the back surface. The row of sliders has segmented scribe lines which are discontinuous across the length of the row. Each slider may also have partial scribe lines, or simply a different pattern of scribe lines on the back surface. The present invention also includes a single slider with partial scribe lines which do not extend across the full width of the slider.
