1. A device comprising:

  • a first read channel to process a first input signal obtained from a Two Dimensional Magnetic Recording (TDMR) storage medium using a first read head, wherein the first read channel comprises a first analog to digital converter (ADC);

    a second read channel to process a second input signal obtained from the TDMR storage medium using a second read head, wherein the second read channel comprises a second ADC;

    a single digital timing loop (DTL) for both the first read channel and the second read channel, wherein the single DTL is configured to control interpolation of timing of sampling for the first and second ADCs; and

    a two dimensional equalizer coupled with output lines of the first read channel and the second read channel;

    wherein the first read head and the second read head are offset from each other in each of two dimensions.
