  • Systems and methods for correcting fabrication error in magnetic recording heads using magnetic write width measurements
    Patent number: 9387568
    Abstract: Systems and methods for correcting fabrication error in magnetic recording heads using magnetic write width (MWW) measurements are provided. One such method includes separating a wafer into sections containing row bars, each row bar including magnetic recording heads, selecting a first row bar from a first section of the sections, lapping the first row bar to form sliders, performing a test of a magnetic write width (MWW) on each of the 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 sliders based on the first error profile, where the component is selected from a magnetic read head and a magnetic write head, and lapping a second row bar from the row bars of the first section using the second error profile.
