Abstract
Data is read from a track of a magnetic recording medium via multiple read transducers located at different positions on a read head. The multiple read transducers are substantially positioned over the track when reading the track. The multiple read transducers have different design characteristics manifesting in differences in at least one of magnetic and electrical behavior of the multiple read transducers. One or more signals originating from the multiple read transducers are combined to assist in decoding the data.
