A manufacturing process for reducing magnetic spacing loss in a magnetic recording
head. The recession of the transducer relative to the substrate at the air bearing
surface is decreased by applying a coating of sacrificial material such as diamond-like
carbon to the upper surfaces of the substrate, the transducer, and the encapsulation
material such as alumina prior to final kiss lapping. The recession due to the
alumina being softer than the substrate is greatly reduced since the DLC is kiss-lapped.
