A magnetic storage system according to one embodiment includes magnetic media containing magnetic domain tracks; and at least one head for reading from the magnetic media, each head having: a first Extraordinary Magentoresistive (EMR) device for detecting magnetic fields of a first magnetic domain track; a second EMR device for detecting magnetic fields of a second magnetic domain track. The system further includes a slider for supporting the head; and a control unit coupled to the head for controlling operation of the head. A system according to another embodiment includes a first Extraordinary Magnetoresistive (EMR) device for detecting magnetic fields of a magnetic domain of interest. A system according to yet another embodiment includes an Extraordinary Magnetoresistive (EMR) device for deriving servoing information.
