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.
