Abstract
A test-device system and method for deconvoluting measurements of effects of a sensor-width definition process from measurements of effects of a sensor-stripe-height-definition process in a manufacture of a magnetic sensor. The test-device system comprises a first test device for generating data to characterize a sensor-width-definition process. The test-device system also comprises a second test device for generating data to characterize a sensor-stripe-height-definition process. The test-device system allows independent characterization of a sensor-width parameter and a sensor-stripe-height parameter.
