Claims

[Scope of utility model registration request]

A data recorder that records a plurality of input signals each containing a DC component and an AC component on a magnetic recording medium, and includes a smoothing circuit that smoothes each input signal, and a holding circuit that temporarily holds each output signal from the circuit. a circuit, a code converter that converts the sign of each of the output signals from the circuit, an adder that adds the output of the converter to the corresponding input signal, and a digital converter for each of the output signals of the holding circuit. An A/D converter, a switching means for selecting an output signal of the converter and a corresponding output signal of each adder, and a recording circuit for recording the output signal passed through the switching means on a magnetic recording medium. A data recorder comprising:
