Claim 22:
23. The data storage device of claim 22, wherein each pair of setting values for the PWM mode comprises a PWM frequency value and a slew rate value of a current applied to or generated by the first VCM, and wherein the one or more processing devices are further configured to:
select a first pair of setting values, the first pair of setting values corresponding to a first PWM frequency value and a first slew rate value;
select a second pair of setting values, the second pair of setting values corresponding to a second PWM frequency value and a second slew rate value; and
select a first PWM change time, wherein the first PWM change time corresponds to a time at which the first VCM transitions from the first pair of setting values to the second pair of setting values for the PWM mode to reduce or minimize the cPES induced in the second VCM; and
wherein the first PWM frequency value is lower than the second PWM frequency value and the first slew rate value is higher than the second slew rate value.
