Abstract
By dimensioning a magnetic playback head so that it coacts with a magnetic signal track having an effective width that is less than one half the shortest signal wavelength to be played back divided by the tangent (or sine) of a predetermined magnetic skew angle that may be experienced by the head, skew angles less than the maximum skew angle will have no effect on the playback of signals having wavelengths greater than said shortest wavelength.
