Abstract
An apparatus for recording and reproducing a signal on and from a record medium includes a reproducing system signal processing circuit (21) for reproducing a recorded information, an output circuit (25) for outputting a reproducing digital audio signal thus reproduced in the form of a predetermined format, an input circuit (29) for converting a signal input from the outside into a signal of a predetermined format and a recording system signal processing circuit (35) for recording at least an information. This apparatus includes switches (20), (23), (27) and (32) for selectively switching the recording and reproducing lines or input and output lines. Since the recording and reproducing lines or input and output lines are selectively switched, all portions that should be diagnosed can be diagnosed. Also, a circuit size can be reduced and a space factor can be improved. Hence, manufacturing cost can be reduced.
