Double coated storage medium for contact transfer recording

Abstract

Abstract A double coated magnetic tape has a relatively thin ferromagnetic layer for storing short wavelength signals and a thicker ferromagnetic layer spaced from the first layer by an intermediate nonmagnetic base for storing long wavelength signals. The thickness of the base and the ferromagnetic layers are selected so that short wavelength signals are efficiently transferred by the thin layer and long wavelength signals are efficiently transferred by the thick layer, the intermediate wavelength harmonics of the long wavelength signals being attenuated by the spacing of the thick layer from a copy tape adjacent the thin layer to which the information is to be transferred.
