Claim Text:
1. A method for enhancing read performance in a multi-reader two-dimensional magnetic recording system including at least first and second readers, the method comprising: receiving a first analog read signal from the first reader and a second analog read signal from the second reader; sampling the first and second analog read signals to generate first and second sampled signals, respectively, each of the first and second sampled signals comprising at least one of an integer component, indicative of a value of a corresponding one of the first and second analog read signals, respectively, at an integer multiple of a corresponding sampling period associated therewith, and a fractional component, indicative of a value of a corresponding one of the first and second analog read signals, respectively, at an arbitrary point in time between integer multiples of the corresponding sampling period; wherein sampling each of the first and second input signals includes: combining at least one of the integer and fractional components of the respective first and second sampled signals to thereby generate a reader offset estimation signal for enhancing read performance in the multi-reader two-dimensional magnetic recording system.
