Abstract

A head for a disc drive and a method of making the head. The head includes a substrate with a trailing side and a first air bearing surface that generates lift. A magnetic transducer is deposited along the trailing side and has a pole tip that is spaced apart from a disc by a pole-to-disc spacing. The head also includes a deposit along the trailing side. The deposit includes a second air bearing surface that changes position relative to the first air bearing surface as temperature increases.
