Abstract

Magnetischer Markierstreifen zur Erzeugung eines Signals innerhalb einer Abtragezone, in der ein sich periodisch änderndes Magnetfeld mit einer vorbestimmten Grundfrequenz vorhanden ist, wobei das vom Markierstreifen erzeugte Signal von einer Abtasteinrichtung aufgenommen und bei Feststellung einer in ihm vorhandenen Harmonischen höherer Ordnung der Grundfrequenz eine Anzeige erzeugt wird, welche aus einem Signalstreifen aus ferromagnetischem Material mit einer geringen Koerzitivkraft besteht, auf den ferromagnetisches Material aufgebracht ist, dessen Koerzitivkraft deutlich größer ist als die des Materials des Signalstreifens, wobei der Signalstreifen gegenüber seiner Breite verhältnismäßig lang ausgebildet ist sowie in einem ersten, unmagnetisierten Zustand infolge des Magnetfeldes im Abfragebereich Harmonische enthaltende Signale abstrahlt und in einem zweiten Zustand in diesem Magnetfeld kein Harmonische enthaltendes Signal abstrahlt, und bei dem das die größere Koerzitivkraft aufweisende ferromagnetische Material in Form von mehreren Kontrollelementen im Abstand voneinander auf dem Signalstreifen angeordnet ist, wobei die Breite der Kontrollelemente im wesentlichen gleich der Breite des Signalstreifens ist und wobei die Kontrollelemente in einem ersten, unmagnetisierten Zustand den Signalstreifen in den ersten Zustand und in einem zweiten, magnetisierten Zustand den Signalstreifen in den zweiten Zustand schalten, dadurch gekennzeichnet, daß der Signalstreifen von einem Band aus einer amorphen, duktilen, nahezu magnetostriktionsfreien Legierung quer zur Längsachse des Bandes abgelenkt ist und daß das Band achsparallel zu seiner Längsachse eine flache B-H-Schleife aufweist.
