1. A system comprising:

  • a reader including a reader head, wherein the reader is configured to(i) receive a first signal from the reader head based on the reader head being at a first position relative to a storage medium, and(ii) receive a second signal from the reader head based on the reader head being at a second position relative to the storage medium, wherein the second position is different from the first position, and wherein each of the first signal and the second signal includes a combination of first data stored in a first track of the storage medium and second data stored in a second track of the storage medium, and wherein the second position is offset from the first position such that the second position is closer to or further away from the second track than the first position; and

    a data determination circuit configured to determine third data stored at a predetermined position of the storage medium using(i) the combination of the first data stored in the first track and the second data stored in the second track as received in the first signal, and(ii) the combination of the first data stored in the first track and the second data stored in the second track as received in the second signal.
