Differing magnetic read sensors on a magnetic head

摘要

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.

1. An apparatus, comprising:
a magnetic head having multiple magnetic transducers, the transducers including read sensors, wherein 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, wherein the head has four modules, wherein a fourth of the modules has read sensors having a greater width in a cross track direction than the read sensors of the other modules.
