Claim:
1. A multi-dimensional equalizer system, the system comprising: a first equalizer circuit operable to receive a first sample set derived from a first read sensor, and to equalize the first sample set to yield a first equalized data set; a second equalizer circuit operable to receive a second sample set derived from a second read sensor, and to equalize the second sample set to yield a second equalized data set; a third equalizer circuit operable to equalize a summed data set to yield a third equalized output; a summation circuit connected to the first equalizer circuit, the second equalizer circuit, and a switch circuit, wherein the summation circuit is operable to sum at least the first equalized data set and the second equalized data set to yield the summed data set; and wherein the switch circuit is movable between a first state and a second state based on a mode of the multi-dimensional equalizer system to either prevent the third equalized data set from being provided to the summation circuit or cause the third equalized data set to be provided to the summation circuit.
