Abstract (en)
[origin: EP2407251A1] The transducer has permanent magnets (1) arranged in rows (R1-R4) adjacent to each other such that magnetic polarities (N, S)assigned to the magnets are periodically alternated with periodic length that corresponds to a track wavelength. Conductor sections (L1, L2) of a high frequency coil arrangement are arranged along rows and run parallel to each other, where the coil arrangement is provided in an opposite direction of current. The permanent magnets are arranged relative to other magnets and displaced around the semi track wavelength.
