1. A slider stability determination circuit, the slider stability determination circuit comprising:
a first signal to noise estimation circuit operable to calculate a first signal to noise ratio associated with a first read sensor; a second signal to noise estimation circuit operable to calculate a second signal to noise ratio associated with a second read sensor; a summation circuit operable to subtract the first signal to noise ratio from the second signal to noise ratio to yield a delta signal to noise ratio; and a stability determination circuit operable to determine a slider stability based at least in part on the delta signal to noise ratio.
