Abstract
A dual-stack read sensor is utilized in a storage device having an actuator arm that positions the read sensor over a rotating storage medium. The dual-stacked read sensor includes a primary read sensor having a first set of read sensor characteristics and a secondary read sensor having a second set of read sensor characteristics that differ from the first set of read sensor characteristics, wherein the secondary read sensor is positioned relative to the primary read sensor to be radially offset from the primary read sensor relative to a data track being read.
