Abstract

PURPOSE:To always ensure the magnetic recording and reproduction with high sensitivity, by having the multiplication between the recording corresponding to a region of high sensitivity and the recording corresponding to a region of low sensitivity for carrying out the recording and reproduction. CONSTITUTION:An input voice signal receives a correction of its frequency characteristics through an equalizer amplifier 3 and is supplied to a mixer 5 via an LPF4. While, an input voice signal of <=500Hz passing through an LPF6 having a low frequency and corresponding to a region of low sensitivity receives an FM modulation through an FM modulator 7 and by the mudulating signal having a frequency approximate to th upper limit of the region of high sensitivity and is supplied to a mixer 5 via a BPF8, etc. The signals having different frequencies corresponding to the region of high sensitivity are multiplexed by the mixer 5 and recorded on a magnetic tape 1 with high sensitivity. The reproduction is also performed in the same way. Thus the information ranging from a region approximate to a DC through a band of a high frequency can be magnetically recorded and reproduced with high sensitivity at all times.
