Abstract of the Disclosure Signals are recorded on a magnetic tape having a magnetic recording layer containing a magnetic material whose magnetic permeability or high frequency loss varies with a magnetic field produced therein. Changes in the permeability or high frequency loss produced according to the recording signals are con- verted into changes in the resonant frequency or Q of a resonant circuit, whereby a reproduced output is obtained.
