摘要：
A tape head, adapted for reading and/or writing to a magnetic tape, has a tape-bearing surface and is configured to urge a magnetic tape against the bearing surface, in operation. The bearing surface includes a transducer area, having at least one transducer that is a read and/or write element, designed for reading and/or writing to a magnetic tape, and a structured area adjacent to the transducer area, comprising a periodic array of topographic features, the topographic features configured within the structured area to determine a minimal distance between the transducer area and a tape.
