Abstract

PURPOSE:To extend a recording time per prescribed length by converting an analog audio signal into a code signal having one bit per sample when converting the analog audio signal into a digital signal, and then by recording the signal. CONSTITUTION:A microphone 1 converts a sound V into an analog audio signal Vs, which is inputted to a CVSD circuit 2 to be converted into a code signal Cs with one bit per sample. This code signal Cs is supplied to a modulating circuit 3, which performs frequency modulation to obtain a recorded signal Rs; and a magnetic head 6 performs recording by varying a magnetic flux corresponding to the recorded signal Rs while a magnetic tape 5 is driven by a driving member 4 at a prescribed speed.
