Abstract
A method, computer-readable medium, and apparatus for measuring properties of a magnetic read head are provided. In one embodiment, the method includes providing a first and a second magnetic read head. A first dimension of the first magnetic read head is different from a corresponding first dimension of the second magnetic read head. The method further includes determining a first change in conductance of the first magnetic read head resulting from an applied magnetic field and a second change in conductance of the second magnetic read head resulting from the applied magnetic field. The first change in conductance and the second change in conductance are used to determine a change in the first dimension and the corresponding first dimension of the first and second magnetic read heads, respectively. The change in the first dimension and the corresponding first dimension results from a manufacturing process of the first and second magnetic read heads.
