ABSTRACT:
Disclosed is an apparatus and method for calibrating the deposition windage of deposited thin film resistive elements, such as magnetoresistive read elements for magnetic heads which are to be lapped, comprising one set of at least three resistive elements having different nominal height dimensions, a resistance detector for measuring the resistance of each of the resistive elements, and a windage calculator responsive to the nominal height dimensions and to the measured resistances of each of the resistive elements for calculating the windage of the one set of resistive elements.
