Claim Text:
1. A method of correcting for fabrication error in magnetic recording heads, the method comprising: separating a wafer into a plurality of sections, each section containing a plurality of row bars, each row bar comprising a plurality of magnetic recording heads; selecting a first row bar from a plurality of row bars of a first section of the plurality of sections; lapping the first row bar to form a plurality of sliders; performing a test of a magnetic write width (MWW) on each of the plurality of sliders; calculating a first error profile for the first row bar based on results of the magnetic write width tests; generating a second error profile for a stripe height of a component of the plurality of sliders based on the first error profile, wherein the component is selected from the group consisting of a magnetic read head and a magnetic write head; and lapping a second row bar from the plurality of row bars of the first section using the second error profile.
