Abstract

PURPOSE:To achieve broad-band analog signal recording and reproduction which has excellent linearity and less distortion, by recording a signal, obtained by modulating a carrier wave on a pulse-duration-modulation basis by an input signal, on a recording medium by vertical magnetization and by reproducing it by a shield type magnetic resistance effect head. CONSTITUTION:A carrier wave of a higher frequency than the frequency band of an input signal is modulated by an input signal on a pulse-duration-modulation basis and the resulting signal is recorded by vertical magnetization on a magnetic recording medium 5. A shield type magnetic resistance effect head 6 composed of a shielding member 6b and a magnetic resistance element 6a arranged at an interval Gs less than the shortest recording wavelength of the input signal and greater than the recording wavelength of the carrier wave reproduces said vertically-recorded signal. For example, a magnetic tape 5 obtained by providing a recording layer 5c, having sharp characteristics of vertical magnetic anisotropy, on a film base 5a across a magnetic layer 5b with high magnetic permeability is used as the recording medium 5, and a vertical magnetization type magnetic head 4 of a main magnetic-pole energization type, etc., is used for recording.
