Lapping monitor element, combined magnetic transducer element and lapping monitor element, and method for manufacturing magnetic transducer element

摘要

Disclosed is a lapping monitor element that is juxtaposed with a magnetic transducer element having a magnetoresistance effect film to determine the lapping position upon lapping the element height of the magnetic transducer element to a predetermined dimension, the lapping monitor element comprising a resistance film to be resistance measured, the resistance film being a metal film of nonmagnetic transition metal or of alloy composed mainly of nonmagnetic transition metal, or a multilayered film where two or more such metal films are laid one upon another, thereby making it possible to extremely stabilize the ELG sensor resistance measured values upon lapping as well as to provide a high accuracy MR height control.
