Abstract:
In one general embodiment, an apparatus includes a magnetic head having at least one tunneling magnetoresistance sensor. The resistance of the tunnel barrier of each tunneling magnetoresistance sensor is about 25 ohms or less. In another general embodiment, an apparatus includes a magnetic head having at least one tunneling magnetoresistance sensor. The resistivity of the tunnel barrier of each tunneling magnetoresistance sensor is less than a product of a target resistance of the tunnel barrier and an area of the tunnel barrier. The target resistance is about 25 ohms or less.
