Abstract
PURPOSE:To achieve broad-band analog signal recording and reproduction which has excellent linearity and less distortion, by recording a signal, obtained by pulse- modulating a carrier wave by an input signal, on a recording medium by vertical magnetization by a specific magnetic head, and by reproducing it by the same magnetic head. CONSTITUTION:A signal obtained by modulating a carrier wave of a higher frequency than the frequency band of an input signal by an input signal on a pulse- width-modulation basis is recorded by vertical magnetization by using a vertical magnetization type magnetic head 5; the tip part of a magnetic head pole 5a with a film thickness TM less than the shortest recording wavelength of the input signal and greater than the recording wavelength of the carrier wave is faced to a magnetic recording medium 6. This magnetic head 5 is used to reproduce said recorded signal. For example, a magnetic tape obtained by providing a recording layer 6c, having sharp characteristics of vertical magnetic anisotropy, on a film base 6a across a magnetic layer 6b with high magnetic permeability is used as the recording medium 6, and a vertical magnetization magnetic head of an auxiliary magnetic pol energization type, etc., is used as the magnetic head.
