| 1. A method of forming suspension mounted sliders whose shapes of an air bearing surface have a more tightly controlled distribution
and a reduced thermal sensitivity comprising:
providing a row bar including a plurality of sliders formed therein;
forming a crowned convex shape of the air bearing surface on said row bar; then
forming a smooth convex shape of a backside surface opposite to the air bearing surface shape on said row bar; then
slicing said row bar to produce individual sliders, the backside surface of each of said sliders having said smooth convex
backside surface; and
mounting each of said sliders on a separate suspension and forming electrical connections between each of said sliders and
said separate suspension on which each of said sliders is mounted.
