ABSTRACT:
A data demodulator is composed of a data separation circuit which produces synchronizing clock pulses from M.sup.2 modulation data which is reproduced by a data recording device and separates the M.sup.2 modulation data into clock bits and data bits, and an M.sup.2 demodulation circuit which produces NRZ - L data by using the clock bits, data bits and synchronizing clock pulses which are output from the data separation circuit. M.sup.2 modulation data which is input to the M.sup.2 demodulation circuit is demodulated to a data signal in NRZ - L format by the demodulation circuit, which has a simple structure.
