<p>This method produces, using a contact magnetic duplication process, a tape (10) having a plurality of recorded segments and separated by cue tones having a reduced tendency to generate false cue tones. The method includes applying a layer of a liquid dispersion to a nonmagnetic substrate. The method also includes the steps of orienting the pigment by applying a magnetic field (50), solidifying the layer of liquid dispersion on the substrate, and applying a demagnetizing field (52) to the layer to neutralize the remanent magnetization.</p> |
