    • A digital signal demodulator is provided for demodulating a reproduced recorded modulated digital signal which includes a parity code. The recorded modulated digital signal has a data code format which may include both valid used data codes and unused redundant phantom codes as a result of an industry standard code format conversion. The digital signal demodulator includes a redundant portion detection circuit which detects whether unused redundant phantom codes are present in the reproduced modulated digital signal data, a demodulating circuit which demodulates the reproduced modulated digital signal, an error detection circuit which effects an error detection using a parity code in the demodulated digital signal to detect erroneous data in the demodulated signal, and a judgment circuit which, when unused redundant phantom codes are detected in the modulated digital signal data, judges the corresponding demodulated digital signal data to be erroneous irrespective of the result of the parity code error detection operation.

    • In a rotary-head digital audio tape system, a reproduced digital signal contains audio data, parities P for the audio data, and parities Q for the parities P and the audio data. The reproduced digital signal is sequentially written in a memory. A code error correction circuit reads the digital signal from the memory and performs code error correction of the digital signal by use of the parities P and Q. The code error correction circuit includes a device for, during the code error correction using the parities P, reading the whole of the written digital signal from the memory. The code error correction circuit includes a device for, during code error correction using the parities Q, reading only the audio data and the parities Q corresponding to the audio data from the memory.
