In a tape recorder in which a recording source signal recorded on the tape recorder is corrected by a noise reduction circuit or an equalizer circuit, and recorded on a magnetic tape with a recording bias signal added, a digital recording source A digital I/O format receiving circuit for input signals, a digital signal processing circuit for processing the received digital data, and a D/A conversion circuit for converting the output signal of the digital processing circuit into an analog signal. What is claimed is: 1. A tape recorder comprising a recording means for recording. 2. The tape recorder according to claim 1, further comprising a recording means for performing correction for canceling distortion of the recording magnetic head by the digital signal processing circuit before recording. 3. The tape recorder according to claim 1, further comprising recording means for performing noise reduction and recording by said digital signal processing circuit. 4. An A/D conversion circuit that converts an analog signal into a digital signal with respect to an input signal of an analog recording source, and a recording means that performs recording signal correction by the digital signal processing circuit and records the result. Claim 1 or 2 or 3 characterized in that
The tape recorder mentioned. 5 In a tape recorder that plays back signals recorded on magnetic tape, A/D converts analog signals into digital signals.
A conversion circuit, a digital signal processing circuit that processes this digital data, and a D/A conversion circuit that converts the output signal of this digital processing circuit into an analog signal, and the tape is played back by the digital signal processing circuit. 1. A tape recorder comprising a reproduction means for performing correction to cancel distortion of a signal and reproducing the signal.
