Abstract

A readback signal from a first reader and a readback signal from a second reader are received, the first reader and the second reader configured to read two-dimensional data from at least one track of a recording media. A quality metric of the second reader is measured based on the readback signal. It is determined if the quality metric for the second reader is above a threshold. If the quality metric is above the threshold, the first reader and the second reader are used to read the data.
