Abstract:
A transducer carrying structure includes a first portion carrying the transducer, a second portion spaced from the transducer, and a spacing control actuation system operable to adjust a position of the first portion of the transducer carrying structure. An overcoat is provided on a surface of the transducer carrying structure. The overcoat has a first thickness in the first region of the transducer carrying structure and a second thickness in the second region of the transducer carrying structure, the second thickness being greater than the first thickness. This configuration provides increased wear robustness to the transducer carrying structure without causing the transducer to be excessively spaced from a medium during operation of the transducer.
