Abstract
A rotating head assembly which is arranged to suppress crosstalk between signals in signal transmission paths to or from erasing, recording and a reproducing heads mounted on a head rotating body, the rotating head assembly including: a plural number of rotary transformers located concentrically around the circumference of a rotational shaft of the head rotating body in spaced positions in a radial direction or in a direction perpendicular to the axis of the rotational shaft; a plural number of substrate boards located in spaced positions in the axial direction of the head rotating body; and a path of signal transmission for the erasing head and/or recording head and a path of signal transmission for the reproducing head routed separately through the rotary transformers in radially spaced positions and through the substrate boards in axially spaced positions to prevent crosstalk between signals being passed the respective signal transmission paths.
