Abstract:
An apparatus according to one embodiment includes a magnetic head having multiple magnetic transducers, the transducers including read sensors. The read sensors are of at least two differing types selected from a group consisting of tunneling magnetoresistance (TMR), giant magnetoresistance (GMR), anisotropic magnetoresistance (AMR), and inductive sensors.
