For reading data tracks, a first virtual boundary of a first data track and a second virtual boundary of the first data track are determined and a reading element is positioned at a center of the first data track based on the determined virtual boundaries. In the system of reading recorded data tracks, a number of forward reading elements and backward reading elements are provided. The forward reading elements have different pitches.
