ABSTRACT:
A magnetic playback apparatus using ferromagnetic resonance of a magnetic material provided with a magnetic anisotropy to develop an anisotropic magnetic field. The magnetic material is disposed at a position influenced by a magnetic field resulting from a signal recorded on the magnetic recording medium. The magnetic material is coupled with a high frequency circuit to be supplied with a high frequency magnetic field. The high frequency characteristics of the magnetic material greatly vary depending on a ferromagnetic resonance. A ferromagnetic resonance magnetic field is set up, allowing for the magnitude of an anisotropic magnetic field and the frequency of the high frequency magnetic field, so that a great variation in the high frequency characteristics due to the ferromagnetic resonance may be obtained according to the signal magnetic field.
