Abstract:
An apparatus according to one embodiment includes a tape head module having an array of at least eight current perpendicular to plane sensors. None of the sensors has a resistance more than about 10% away from the resistances of its nearest neighbors. An apparatus according to another embodiment includes a tape head module having an array of at least eight current perpendicular to plane sensors. The resistance of each sensor is within about 10% of the median resistance value of all sensors in the array.
