Abstract
An apparatus for measuring magnetic recording head transducer to disc surface spacing and a method of fabricating the same are disclosed. A slider body of a read/write head has first and second rails forming portions of an air bearing surface of the slider body. First and second cavities are formed in the first and second rails of the slider body at the air bearing surface. First and second capacitance plates are positioned within the first and second cavities, respectively, such that a surface of each of the first and second capacitance plates is substantially coplanar with at least portions of the air bearing surface.
