摘要：
A digital signal recording/reproducing apparatus having a mode for recording a compressed input signal on a recording medium and a mode for recording a non-compressed input signal on the recording medium. The apparatus include input circuits which input a digital compressed signal and an analog non-compressed signal, an A/D converter, a data compressor, a mode change-over circuit which changes-over the mode, and a selector which selects either a digital compressed signal from the data compressor or a digital compressed signal from the input circuit. A recorder records a recording signal to a recording medium and a reproducer.
