Abstract

First and second tracks of a magnetic recording medium are read simultaneously via a first reader that provides a first signal based on detecting a total perpendicular field of the first and second tracks. The first and second tracks are read simultaneously via a second reader that provides a second signal based on detecting a total longitudinal field of the first and second tracks. Data is detected from the first and second signals.
