Abstract

Abstract Translated from German Um beim Aufzeichnen von Tönen auf magnetische Bänder eine geringe Bandgeschwindigkeit bei Erhaltung der hohen Frequenzen zu erhalten, wird die Abnahme der Begrenzungskurve des Feldes des Sprechkopfes steil gemacht dadurch, daß das Produkt aus Dicke der Magnetschicht und ihrer Permeabilität weniger als 100 ist. In order to obtain a low tape speed while maintaining the high frequencies when recording sounds on magnetic tapes, the decrease in the limiting curve of the field of the speaking head is made steep by the fact that the product of the thickness of the magnetic layer and its permeability is less than 100.
