A method for adjusting the pitch and roll static torques (PST and RST) on
a slider in a disk drive head-suspension assembly (HSA) during
manufacturing assures that each HSA is manufactured with acceptable PST
and RST values. The method includes measuring each slider's pitch and
roll static attitudes (PSA and RSA) and determining each HSA's pitch and
roll torsional stiffnesses. These values are then used to calculate the
required amount of adjustment to PSA and RSA to achieve the desired
values of PST and RST for each HSA. The suspension is then adjusted, such
as by heating the flexure with a laser.
