DEGAUSSER FOR TAPE USED WITH CONTACT DUPLICATION

This method produces a tape (10) having a plurality of recorded segments having a reduced tendency to generate errant control track pulses. 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...

Summary:This method produces a tape (10) having a plurality of recorded segments having a reduced tendency to generate errant control track pulses. 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, solidifying the layer of liquid dispersion on the substrate, and applying a demagnetizing field to the layer to neutralize the remanent magnetization. Ce procédé permet d'obtenir une bande magnétique (10) comprenant une pluralité de segments enregistrés qui présentent une tendance réduite à la production d'impulsions erratiques sur une piste d'asservissement. Il consiste à appliquer une couche d'une dispersion liquide sur un substrat non magnétique, à orienter le pigment par application d'un champ magnétique, à laisser solidifier la couche de dispersion liquide sur le substrat et à lui appliquer un champ démagnétiseur pour neutraliser la magnétisation rémanente.
