Abstract: A method of making a transducer head disclosed herein includes depositing a spacer layer on an NFT layer of the transducer head, forming an etch stop layer on a spacer layer of a transducer, depositing a cladding layer on the etch stop layer, and milling the cladding layer at a sloped angle such that the milling stops at the etch stop layer.
