Analog information may be written on magnetic tape in several forms. In direct or bias recording, magnetization (less a constant bias) is proportional to the input, in FM or frequency modulation (q.v.) information is carried by variations of a carrier-wave frequency, in pulse-width modulation (q.v.) by variations in the width of square-wave pulses. See Figure M-16.
