摘要： An apparatus for reproducing a signal recorded, in the form of a perpendicular signal magnetization, on a perpendicular magnetic recording layer backed with a high permeability layer of a magnetic recording medium. A thin-film magnetic material is disposed to face the recording layer so that an enlarged magnetized region is formed in the high permeability layer, which includes the position at which the magnetic material faces the recording layer. In this region, magnetic variation occurs in response to the signal magnetization of the recording layer at the position the magnetic material faces the recording layer. A detecting member such as a coil is disposed in the proximity of the magnetic material so as to be magnetically coupled to the enlarged magnetized region of the high permeability layer. The detecting member is used as a tuning element of a tuning circuit supplied with high frequency energy. A resonance output voltage of the high frequency circuit varies in response to the detection of magnetic variation in the high permeability layer. A reproducing circuit detects the variation in the resonance output voltage of the high frequency circuit to reproduce the signal recorded on the recording layer.

摘要： A magnetic recording head apparatus includes: a magnetic head body opposing a travelling magnetic tape; a tuning circuit having the head body as a variable inductance element; a high-frequency signal source for generating a high-frequency signal; and a detector connected to the tuning circuit. The inductance of the head body is changed in accordance with a change in the magnetic signal field applied from the magnetic tape. The high-frequency signal is amplitude-modulated in accordance with the high-frequency signal. A peak or envelope waveform of the modulated high-frequency signal is detected by a detector, thereby obtaining a reproduced information signal.

摘要： 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.
