Abstract
An apparatus for reading data includes an array of analog inputs operable to receive analog signals retrieved from a magnetic storage medium, wherein the analog inputs correspond to multiple data tracks on the magnetic storage medium, and wherein the number of analog inputs in the array of analog inputs is greater than the number of data tracks being read, at least one joint equalizer operable to filter the analog inputs to yield an equalized output for each of the data tracks being read, and at least one data detector operable to apply a detection algorithm to the equalized output from the joint equalizer to yield detected values for each of the data tracks being read.
