Abstract:
System and methods are illustrated for customizing the HGA bonding skew angle of a TDMR slider including a plurality of readers to adjust reader alignment relative to a track location on disk media. Overlay error caused by manufacturing variations is compensated for by adjusting the skew angle of the slider when it is bonded to the suspension to form the HGA. Process operations for manufacturing a TMDR HDD include manufacturing a multiple reader, multiple layer TDMR slider, determining an overlay error in the slider, determining a slider bonding skew angle based on the determined overlay error and other parameters, and bonding the slider to a HDD suspension at the determined bonding skew angle.
