New helical recording scanner architectures and transducing methods provide a consistent track pitch for helical tracks despite positional errors in placement of transducing elements from their nominal positioning. The implant includes an expandable central portion formed of a first material that at least partially inhibits the monitoring of bone in-growth using a medical diagnostic technique. According to one aspect of the invention, a plurality of continuous active areas are formed relative to a semiconductive substrate. The ceramic green laminate is sintered to produce a ceramic laminate.
